decimal . or , interchangeable

Ondřej Čada — 2012-04-26T15:13:36

Hello again,

the client want me to change a pretty old and pretty big WO application so that both '.' and ',' work interchangeably for a decimal point on input, in all fields of all forms.

I know a number of ways to do that for a specific field, but before I dive into that, isn't there a way to say globally for an entire WO application: "Hey, whenever and wherever you are converting a string to a number, consider '.' and ',' equal"? That would help a lot.

I went through the NSNumberFormatter API, but found nothing :(

Thanks and all the best,

setPageRefreshOnBacktrackEnabled problem?

Ondřej Čada — 2012-04-26T13:17:19

Hello there,

either setPageRefreshOnBacktrackEnabled does not work, or I am missing something fundamental.

In my "class Application extends ERXApplication" I do "setPageRefreshOnBacktrackEnabled(true)". All the HTTP headers are generated all right, far as I can say:

Weird OGNL problem?

Ondřej Čada — 2012-02-26T00:24:42

Hello there,

at the moment, I'm getting the following exception. Can anybody see where the null extra argument got from? I'd be grateful for any advice:

WOLips HTML formatter woes

Ondřej Čada — 2012-02-23T11:00:48

Hello there,

is it possible to make the thing *not* to turn accented characters to HTML entitites?

When I put "á" into my UTF-8 HTML template, I'd rather it stayed "á"; that it gets turned into &aacute; is extremely annoying.

access to enclosing component bindings?

Ondřej Čada — 2012-02-22T12:21:45

Hello there,

in a structure similar to

<wo:repeat ... list="$something.out.there">
  <wo:MyComponent partOfList="$something.out.there"/>
</wo>
<wo:repeat ... list="$another.list.here">
  <wo:MyComponent partOfList="$another.list.here"/>
</wo>
<wo:repeat ... list="$and.just.another.one">
  <wo:MyComponent partOfList="$and.just.another.one"/>
</wo>

if would be pretty convenient if I could implement MyComponent so that instead of binding its "partOfList" explicitly, it finds the enclosing WORepetition (innermost if more, crash if none) and reads in its list binding.

Is it possible? If so, can you please point me to some hint/example/doc of howto?

Thanks a lot,

Barcode with iText

Louis Demers — 2012-02-22T00:26:21

Hi,

I'm trying to create barcodes with iText without inserting them into a PDF, but instead for inclusion into a wocomponent. The barcode is returned as a com.itextpdf.text.Image but I can't figure out how to get a usable image for woimage. Alternatively, I could get a java.awt.Image, But I'm equally dum and clueless with those.

Any past experience and pointers would be welcomed.

Cordially.

Quick OGNL question

Ondřej Čada — 2012-02-21T14:33:05

Hello there,

among others, I'm exploring the WOOgnl power (quite nice stuff!)

Now I've got a subcomponent whose bindings are "auction" and "field". Auction has methods

// Auction -- the object to which the component's "auction" binding leads
String listFieldValue(Field field) { return .... }
void setListFieldValue(Field field, Strin val) { .... }

The subcomponents contains, among others,

<wo:textfield value = "~auction.listFieldValue(field)"/>

and I was rather surprised seeing the form gets created properly -- the OGNL thing is quite nice :)

Of course, as you probably guessed long ago, self-evidently the form can't save with this binding. Now, is there an OGNL trick to fix it in the HTML/WOD so that it does save all right, or do I have to implement glue code in my component and bind to that, like

// Component glue code
String listFieldValue() { auction.listFieldValue(field) }
void setListFieldValue(String val) { auction.setListFieldValue(field,val) }

<!-- and new binding -->
<wo:textfield value = "$

form woes

Ondřej Čada — 2012-02-19T21:25:10

Well, a few hours ago I've set up my first file uploading form in WONDER/WOLips/WO 5.4.3.

Incredible fun.

As soon as I've set up "multipart/form-data", I've stopped getting my action. That one was comparatively easy -- I just had to copy the action from the submit button binding to the form binding.

As soon as the action was fixed, it got couriouser and couriouser -- I've found I'm not getting any form data.

Overriding takeValuesFromRequest at all levels I've found that both application and session get the form all right, in other words, the ERXRequest's formValues does contain proper data there. Nevertheless, at the very beginning of component's takeValuesFromRequest the form gets weirdly re-interpreted -- formValues are empty; on the other hand, the ERXRequest body is nonempty now.

Spending some time googling I've found this happens when encodings are switched; nevertheless, I do not switch encodings at all. At the beginning I set ERXMessageEncoding.setDefaultEncodingForAllLanguages("UTF-8") and that'

sql to update existing database?

Ondřej Čada — 2012-02-19T14:09:14

Hello there,

is there a script or Entity Modeller tool or whatever to generate a "diff" SQL for given model and existing database, so that tables get created for new entities, but updated (by adding columns) for the already existing ones?

Seems to me basic enough functionality for someone already have done that, but can't find anything on the web...

Thanks and all the best,

WOComponent editor

Ondřej Čada — 2012-02-11T07:34:25

Hello there,

there are a couple of things I seem not able to find an answer on the web -- if you could help perhaps...

(a) is there a way to switch betw. the inline (<wo:string value="$foo"/>) and classic (<webobject name=Foo/> in html, Foo:WOString { value=foo; } in wod) patterns automatically, without having to re-write and copy/paste manually? Some smart script which could do that in batches based on list of tags and number of bindings would be about perfect, but even a shortcut which would work over one selected tag would help.

(b) happens somebody to know what's the difference betw. HTML and WOD Content Assist? For my java components they both work consistently. The weird thing is, for my groovy components the HTML Content Assist works just as well as it does for java ones; nevertheless, in WODs it does not offer anything from the class. Though I supposed it would not work at all with Groovy, seeing  it works in HTML perfectly, I'd like to fix the problem in WOD, if possible?

And writing the above,

Weird case of "The requested application was not found on thisserver"

Ondřej Čada — 2012-02-09T06:48:50

Hello there,

looks like I've licked most of the Eclipse/WONDER/Groovy problems by now (but for WOGroovy, that one's still in queue), and I've bumped into one weird problem.

When I run my built application manually from Terminal, like "./Test.woa/Test -WOPort 56000", then the "http://localhost/cgi-bin/WebObjects/Test.woa/-56000" URL does not work -- consistently yields "The requested application was not found on this server".

Direct connect (http://localhost:56000) works all right (assumed I use -WODirectConnectEnabled of course).

If I set up the very same application in JavaMonitor and access through "http://localhost/cgi-bin/WebObjects/Test.woa", it _again_ works all right!

Finally, to make it couriouser and couriouser, when I run manually from the Terminal an _older_ application, a pre-5.4.3, Xcode-built one, the "...Another.woa/-56000" URL _does_ work all right :-O

So, the only case which does not work is a newly ant-built one manually run and accessed through ...woa/-port.

Since both direct connec

Eclipse / Groovy

Ondřej Čada — 2012-01-24T12:26:12

Hello there,

since I've more or less finished the project in which I've used lately ERMail only and since there were rather problems with that (though it does work), I've decided to try to embrace complete WONDER (and, to this goal, sadly leave Xcode and go Eclipse). Also, as an added benefit, I'd like to use Groovy along with (and, hopefully, increasingly instead of) the Java thing.

I've installed the stuff using the tutorials at the wocommunity wiki, and am reading through the other docs, but there are a couple questions I'd like to ask you more experienced people out there:

1. Eclipse: for someone who spends most time in Xcode, the thing's GUI's a proper disaster :( Did someone succeed to make it at least a bit Mac OS X'y? If so, would you share the tricks?

So far about all the customization I was able to find howto are some changed hotkeys (e.g., (shift)-cmd-g for find prev/next), but I've found so far no way to make it heed the find pasteboard or use cmd-e properly, I haven't found a way to open a s

Deployment problem

Stavros Panidis — 2011-10-19T13:01:15

Hi all,

I am trying to deploy an application in a Snow Leopard server (10.6.8).

The server is running for some years successfully and two other WO applications are already installed and running without any problem.

I use JavaMonitor and wotaskd provided by Apple.

Using JavaMonitor I add an instance of the application, which comes on line after a while.

When I try to access the application I get the message 'No instance available.

Any help?


Many thanks in advance

Stavros

AjaxModalDialog in iframe

Pierre Gilquin — 2011-09-21T12:50:31

Hi,

I use an AjaxModalDialog in an iframe. When started the dialog is restricted with the size of the iframe. Is there a mean to launch it from the parent content ?
something similar to target=_top ?

Thanks in advance

WORedirect and %-escapes?

Ondřej Čada — 2011-09-09T15:33:55

Hello there,

looks like this should be a trivial problem with trivial solution, but probably having my dumb day I can't find a simple one.

I've got an URL (to a static file on a server), whose name contains accented characters. When this URL, with the accents and all, was bound to WOHyperlink.href, it worked flawlessly.

Now though I need to return the same URL through a WORedirect, and I've bumped into a problem.

WORedirect tries to be smart, and translates accents to %-escapes. The catch is, it uses some Latin encoding, and thus e.g., 'á' (a acute) translates to %E1. That's wrong though, since the encoding needed to access files on the web server is UTF-8; thus, the 'á' must be translated to %C3%A1, if at all.

Do you happen to have any hint to

(a) make WORedirect use UTF-8 for %-escapes, or
(b) do UTF-8 %-escapes programmatically before I set the url to WORedirect, or
(c) make WORedirect not to %-escape at all, which does provably work all right?

Thanks and best,

ERJavaMail problem

Ondřej Čada — 2011-09-07T05:01:51

Hello there,

I've bumped into another problem. Since I need a bit more for mail than WOMailDelivery can give, I've decided to use ERJavaMail.

I went by this quickstart recommendation:

http://homepage.mac.com/kelleherk/iblog/C183784902/E2093239404/index.html

First problem was that I've kept getting the "When setting 'er.javamail.centralize=true' (which means you just test sending mails), you must also give a valid 'er.javamail.adminEmail=foo< at >bar.com' to which the mails are sent" error, although the Properties are set up all right.

Well I've downloaded the Wonder sources too, and quickly found the cause is that the quickstart self-evidently forgot to point out that one must first send the initializeFrameworkFromSystemProperties to the ERJavaMail shared instance. Never mind, I've added the intialization.

Nevertheless, from the method I kept getting null pointer exceptions. Digging deeper into the source and trying it step by step I've found the cause to be the ERJavaMail.isValidEmail method, which raises

target _blank and refresh original page

Ondřej Čada — 2011-09-01T01:54:59

Hello there,

seems a rather usual task, but I can't find a decent solution nor google out one.

I've got a WOHyperlink which returns something (through WORedirect, though I don't think that's important) in a new window -- i.e., I've set target=_blank in the WOHyperlink bindings.

The trick is that I would need to refresh the original page too: my code looks more or less this way

String theResult; // bound to a WOString in the page
WOActionResults showFooInExtraPage() { // bound to a target=_blank WOHyperlink
  WORedirect wor=new WORedirect(context());
  wor.setUrl( ... computed somehow, irrelevant, works all right ...);
  theResult="Thanks for getting "+wor.url();
  return wor;
}

How to make the original page to reflect the new theResult value automatically without waiting till the user does something to refresh it manually?

About the best I can think of is to refresh the page all the time, but that would be *quite* ugly and inconvenient -- the user might not use the WOHyperlink at all, and it would seem

Wonder deploy problem on linux

Pierre Gilquin — 2011-08-26T09:55:54

Hi list,

I just start to use wonder and I made a first test with Ajax / UpdateDisplayGroupExample.
I am developing  with WO 5.3.3 / Wonder 535 on Windows.
I try to deploy on Linux my test app with the same versions. 
On linux, I have javascript errors :
$(form).fire is not a function
 $(form).fire('ajax:submit');  in wonder.js (line 406)

As far as I know everything is identical (versions /test app) on windows and linux.

Any idea why this error on linux ?

Thanks in advance.

EOQualifier, contains, and a pair of relationships

Ondřej Čada — 2011-08-15T18:36:35

Hello there,

possibly I do something wrong, but can't see what -- any help please?

I need to filter by a presence of another object in a two-level N:1/M:N relationship. Means that an enterprise object X should be displayed in the DG iff its relToOne leads to any Y whose relToMany contains Z.

Well, what I do is

EOQualifier.qualifierWithQualifierFormat("relToOne.relToMany contains %< at >",new NSArray(Z));

is that conceptually right?

Anyway it does generate _almost_ proper SQL; alas, in one place there's a LIKE instead of =, namely (cleaned up from the unimportant stuff)

SELECT
  t0.C_CREATION_DATE, ..., t0.C_UID FROM T_AUDIT AS t0,
  T_USER_GROUP_USER AS T2,
  T_USER_GROUP AS T3,
  T_USER AS T1
WHERE (T3.C_UID LIKE 1000004) AND (T1.C_UID=T2.C_USER_ID) AND (T2.C_GROUP_ID=T3.C_UID) AND (t0.C_CREATOR_ID=T1.C_UID);

Any idea what do I do wrong and what causes the nonsense LIKE there? Had there be a = instead, it would work like a charm.

Or -- I admit I am no SQL guru -- should the LIKE work and it is a fault o

Check if framework was included in application

Miguel Angel Torres Avila — 2011-04-05T17:54:49

Hi list,

I am working in a new framework that encapsulates all the functionality of an entire module. The idea is just to include this framework in any application and voila! a new menu is included and the user can interact with it and all the module's functionality.

Of course it is no that easy and now I need to know if there is a way to know if a Framework is included in the application to decide when to run certain processes to create the connectivity between the application and framework.

Does anybody know if there is a function to accomplish the verification of the presence of determined framework?
