DropDownChoice and onSelectionChanged error.
Hi;
I have a problem with DropDownChoice; The code block is here :
List<Faaliyet>faaliyetListesi = // data comes
final DropDownChoice<Faaliyet> faaliyetler =
new DropDownChoice<Faaliyet>("Faaliyetler",
new Model((Serializable) faaliyetListesi),
faaliyetlerRenderer) {
@Override
protected boolean wantOnSelectionChangedNotifications()
{
return true;
}
@Override
protected void onSelectionChanged(Faaliyet newSelection)
{
super.onSelectionChanged(newSelection);
PageParameters params = new PageParameters();
params.add("ay", finalAy + "");
params.add("yil", finalYil + "");
params.add("faaliyetId", newSelection.getId() + "");
setResponsePage(ActionPage.class, params);
}
};
add(faaliyetler);
The error message is :
wicketMessage: Method onSelectionChanged of interface
org.apache.wicket.markup.html.form.IOnChangeListener targeted at
component [MarkupContainer [Component id = Faaliyetler]] threw an
exception
Root cause:
java.lang.IllegalStateException: Attempt to set model object on null

Maybe you can post additional details... and then maybe someone can spot
what's happening.

RE: javscript header contribution in lazy load panels
Posted by Stefan Lindner <li...@visionet.de>.
It is added and a test script with an alert command tells me that it is executed too. But things like jQuery don't work.
When I drop the lazy loading and replace it with the lazy loaded panel everything works.
When I redraw the wohle panel in an Ajax call, everything works too.
It's just the fact
1. having the javascript librarys loaded in the pages header section one time on the first page rendering heals all
2. having the javascript librarys loaded in the lazy loading ajax dom replacement it works only in IE. Even if the scripts are executed.
I know, this may be a jquery/otherlib problem but perhaps someone else ever had this effect and found a workaround.
Stefan.

RE: javscript header contribution in lazy load panels
Posted by Stefan Lindner <li...@visionet.de>.
I have some Behaviors that extend AbstractDefaultAjaxBehavior. In the renderHead method of the Behaviors I use
public void renderHead(IHeaderResponse response) {
response.renderJavascriptReference(WicketEventReference.INSTANCE);
}
But that's not the problem. When I look into Ajax debug output I can see that the resource references are rendered correct. AND: in IE this works. This must be some sort of jQuery internal problem or some security problem in FF.

How do you add the JavaScript? I have pages where components are added via
AJAX, which include JavaScript and CSS via
add(JavascriptPackageResource.getHeaderContribution(ResourceReference...));
and this works fine in any browser I have tested (IE, FF, Chrome, etc).

javscript header contribution in lazy load panels
Posted by Stefan Lindner <li...@visionet.de>.
Dear wicket users,
I have a lazy loading panel. The components inside the generated panel (i.e. the panel that is generated inside the getLazyLoadComponent method) have some header contributing ajax behaviors (jQuery etc.).
The lazyly loaded components render javascript resources to the head section oft he page.
When the page is created, the header does not contain any <script src="..."> tags. That's clear because wicket does not know which resources are needed by the lazyly loaded panel. The <script src="..."> tags are part of the ajax answer.
IN IE this works well but in other Browsers (Firefox, Chrome, Safari) the javascript functionality does not work.
We have to put the <script src="..."> manually into the parent page.
Is this a known behavior? Does anybody know a magic trick to get the javascript librarys working that are part oft he ajax response?

If you use the below constrcutor, it should solve your problem.
DropDownChoice(java.lang.String id, IModel model, IModel choices,
