Change philip-20130506-t0j by philip&lt; at &gt;philip-i7-2 on 2013-05-06 20:42:11 EDT     in /cygdrive/f/clients/laszlo/svn/openlaszlo/trunk     for http://svn.openlaszlo.org/openlaszlo/trunk Summary: Improve performance of html component New Features: Bugs Fixed: LPP-10276 Technical Reviewer: (pending) QA Reviewer: antun Doc Reviewer: (pending) Documentation: Release Notes: Overview: Details: I think some recent changes I made to reduce closures resolved the memory leak (I did not observe them during testing). I did make a change to cache the location of the iframe to improve performance. The update runs via the idle timer and monitors the iframe position and zoom value. Most of the method is needed only when the window size changes. Tests: Test case in jira. I do not see a memory leak in IE9, but I suspect this is from an earlier change where I removed a bunch of closures. I did enable some code to cache the position of the iframes. Performance improvement is only about 1%, but it should help reduce any flickering when the iframe is moved.

Sorry not to be able to provide more info, but that example should be instructive to follow. Feel free to ask questions.

For the SWF10 runtime, I get the following error: org.openlaszlo.sc.CompilerError: ../../app/lzx/test/playground/styledview/types-css.lzx: 36: Error: Access of undefined property $lzc$class_MyType, in line: Debug.info(value_$0 is $lzc$class_MyType); When I set the class name to $lzc$class_MyType instead of just MyType, everything works as expected. Thanks again!

I did some more testing: it's actually the attribute's setter method which is being called with a string value when I use an inline attribute value. In case of a value set through CSS, an instance of the new type is created on the fly and passed into the setter. The only question left: Why isn't it possible to test for the class using the 'is', e.g. if (value is lz.MyType) for this type definition: class MyType { var _value; function MyType(val) { Debug.info('MyTpe constructor: value=', val); this._value = "processed value: " + val; } function convertToString() { return _value; } } lz.MyType = MyType; I've attached the source of my small test app for anyone else interested. Thanks, Raju </pre> Raju Bitter 2013-04-16T22:12:55 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28803 <pre>The intent was that for custom types you write an accept method that knows how to parse the CSS representation (a string) into the internal representation (an instance of your custom class) and that is passed as the value of the attribute. Some useful links might be here: http://www.openlaszlo.org/lps4.9/docs/developers/css.html#dynamiccss http://www.openlaszlo.org/lps4.9/docs/developers/debugging.html#explaincss http://thread.gmane.org/gmane.comp.java.openlaszlo.devel/26537/focus=6569 Although you have probably already found all of those. I had started, but not finished (as I recall) the ability to create additional types in LZX.

I have a . custom type with a constructor defined. When setting the attribute at runtime, the type's &lt;accept&gt; tag is used to trigger the instantiation of the new type instance. When I set the value using CSS, the constructor of the type is called, passing an instance of the type instead of the CSS property value. Is there any documentation online for the type system? - Raju </pre> Raju Bitter 2013-04-16T21:14:07 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28801 <pre>I found another bug with the boxmodel mixin and the basefocusview. The basefocusview sets the dimensions of a view ignoring possible borderwidth values &gt; 0, meaning the focus rectangle is smaller than the target view with borders. http://jira.openlaszlo.org/jira/browse/LPP-10352 - Raju </pre> Raju Bitter 2013-04-11T01:09:15 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28800 <pre>I think Webtop is still being used, not that I've heard of any new customer announcements since Laszlo has been acquired. But that's probably due to the zero marketing activity we have seen. Laszlo used to have an active announcement mailing list, but that has been dead since August 2010: http://www.openlaszlo.org/pipermail/laszlo-announce/ Last announcement there was the 4.8.1 release. Laszlo/CP has been doing development, although the number of commits is much lower than it used to be. People kept telling me that Laszlo/CP is still fixing bugs, but most of the features which have been added in the past 4 years have not been tested well or haven't received decent QA - due to lack of community members testing the platform and lack of resources on the Laszlo side. - Raju </pre> Raju Bitter 2013-04-10T13:05:05 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28799 <pre>When I subscribed the list I got this automated message from Laszlo Systems (not CP!): "The mailing lists are hosted by Laszlo Systems, but Laszlo Systems employees participate in the lists as members of the community, essentially on their own time and in the spirit of the collaborative nature of any open source project. In particular, the lists are not an official support mechanism and you should not expect an answer to any particular question, from Laszlo Systems employees or anyone else." Note this sentence: "In particular, the lists are not an official support mechanism and you should not expect an answer to any particular question, from Laszlo Systems employees or anyone else." The welcome message needs to be updated, unless CP is trying to hide the fact that OpenLaszlo is a Critical Path product right now. It looks like the Critical Path Webtop system is a dead product. They try to create a nice marketing message: http://www.cp.net/index.php/news-2/280-news-radicati-top-player "The Radicati Group names Critical Path ‘Top Player’ ... Messaging platforms are robust, highly scalable, brandable, and localizable offerings." How robust and stable is your messaging platform if you don't maintain one of the key platforms you are using for building highy-priced products. Critical Path has a bad reputation anyway, haven't heard anything good about the company from people in the Bay Area and people working for one of the other companies they acquired. I wouldn't be surprised if all former Laszlo employees have left the company by now.

I've never seen the OpenLaszlo platform in such a state in the past 8 1/2 years. Is there anyone within the management at CP aware of those bugs, and are those bugs going to be addressed? If not, the platform will become be unusable very soon. - Raju </pre> Raju Bitter 2013-04-09T14:34:11 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28797 <pre>In DHTML runtime, getMouse() adds the borderwith values to the x/y position of the mouse pointer. containsPt() uses those incorrect values and is broken as well. http://jira.openlaszlo.org/jira/browse/LPP-10351 I'll assign the issue to Amy, since Max does not seem to be active any more. - Raju </pre> Raju Bitter 2013-04-09T14:28:18 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28796 <pre>Doesn't "sound" like there's any serious QA being done. Is there any interest left by developers inside/outside Laszlo to cooperate fixing these bugs? For the project I'm working on, I'd be willing to assemble a list of all the bugs related to drawview/sprite and rounded corners, drop shadows as well as background rendering. If those bugs are fixes, at leased the platform can be used. If not, it's pretty useless. - Raju </pre> Raju Bitter 2013-04-09T13:08:50 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28795 <pre>There's a but in the LzCanvasGradient class for linear gradients in SWF runtime.

Here's the link to the JIRA issue, forgot to add that to my last message: http://jira.openlaszlo.org/jira/browse/LPP-10349 </pre> Raju Bitter 2013-04-07T20:54:05 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28793 <pre>Is Critical Path / Laszlo still working on a new component set for OpenLaszlo? Looking at the number of bugs I'm running into when using the drawview component with features like rounded corners and drop shadows it seems that there's no much QA being done at the moment. Are any other developers using these features for their apps? Without some serious bugfixing and QA work drawview and some of the LFC APIs for drop shadows and rounded corners are pretty broken. If we provide patches and bug reports, is there any interest in actually fixing those bugs? And is a 5.0 release realistic for 2013? - Raju </pre> Raju Bitter 2013-04-07T20:52:10 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28792 <pre>Thanks, Max. </pre> Raju Bitter 2013-04-06T16:47:17 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28791 <pre></pre> Nico Voss 2013-03-28T15:31:41 http://permalink.gmane.org/gmane.comp.java.openlaszlo.devel/28790 <pre>I still read the messages, but have been so busy with telcom work i have not been able to respond.

But a 5.0 release would be a good for all of us (CP, OpenLaszlo, community). I'm still using OpenLaszlo at the moment, and all the bugs I'm reporting or where I'm providing patches are things which I need for the application I'm working on.
