Regardless, try removing the '#' from the oninit handler, to get: <handler name="oninit" args=""> <![CDATA[ /* this text color is black !! */ textComponent = new lz.text(this,{x:"10",y:"35",fgcolor:"FFFFFF",fontsize:"18"}); textComponent.setText("Test"); ]]> </handler> see if that helps.

This may be obvious. If your question is how to *reparent* a view from one container to another - the short answer is, you can't. The best pattern to use here is to save all the related parameters that compose the view being dragged and create a new view under the desired new parent and copy those parameters over. If you use that pattern, a simple copy/paste manager for that type of dragged object that will automatically do that given the object and the new parent is a good way to go. Did this help?

If I create an LZ object, can I use 'delete' to delete the object instead of using "destry()" member function? The reason I ask this question is that 'destroy()' performance is very bad. Create an array of 50 objects, and then use 'destroy()' to destroy them, you will see the browser is basically frozen for a few minutes. But if I use delete, it runs very fast. Thanks!

Regards, Ken Kenneth Miller 2008-08-15T21:32:18 http://permalink.gmane.org/gmane.comp.java.openlaszlo.user/5053 Is it possible to add a complex LzDataElement (multiple children) directly to a dataset? This seems overly complex. I'm replicating over a series of nodes, generating some viewable areas and a form at the bottom. I assemble an LzDataElement in the onmousedown event of the forms submit button. I understand that I can set up a new datapointer, point it to the same node in the dataset as it's parent replicated datapath, and then add a single node, but how can I append a complex LzDataElement? Regards, Ken Kenneth Miller 2008-08-15T05:05:03 http://permalink.gmane.org/gmane.comp.java.openlaszlo.user/5052 Hi there, I am having a problem with the class 'tree'. In the code below, I create a list. When an entry in the list is clicked, it creates an instance of 'tree'. But the list clicking does not work properly. For instance, click the first entry, then use the scroll bar to scroll the list to the end of the list and then click the last entry, the list somehow jumps back to the last entry of the shown items before scrolling. Try to select an entry, use the scroll bar to make the selected entry unseen, and then select another entry, you should see the problems. But note that if I do not scroll the list, everything works perfectly. If I create a push button instead of a tree node when an entry is clicked, everything works just fine (i.e., uncomment Line 11 and comment out Line 10 in the code below). Your help is greatly appreciated!

Try value="null", for example, or " '' " (that's single quotes in double quotes) if you need a zero length string rather than null. Sorry about the error message, we need to improve the parser to be able to report a location instead of getting totally confused by missing value. Can you file a bug with this example, to improve the compiler error (if there isn't one already).

I'm guessing the smallest test case would be: <canvas> <attribute name="z" value="" /> </canvas> At the very least, the compiler should give you a more informative message. But the question is, do you want the compiler to complain if you have said you want the attribute to have a value, but failed to give it a value (the double-quotes are not part of the value)? Or do you want the compiler to assume that you didn't mean to give it a value after all? Under the covers, the reason you are getting an error is what you wrote: <attribute name="z" value="" /> translates into the following Javascript: var z = ; which is not valid.

My brief testing with 4.2alpha didn't go so well, I'll wait for the beta to be more thorough.
