Andreas Kappler created WICKET-4911:
---------------------------------------
Summary: Palette Ajax update does not work
Key: WICKET-4911
URL: https://issues.apache.org/jira/browse/WICKET-4911
Project: Wicket
Issue Type: Bug
Reporter: Andreas Kappler
Javadoc of org.apache.wicket.extensions.markup.html.form.palette.Palette
describes a method of receiving ajax updates when the selection has changed:
Palette palette=new Palette(...) {
protected Recorder newRecorderComponent()
{
Recorder recorder=super.newRecorderComponent();
recorder.add(new AjaxFormComponentUpdatingBehavior("onchange")
{...});
return recorder;
}
}
Prior to wicket 6 this worked, but the jQuery integration broke this
functionality. The problem lies in palette.js line 127:
if (recorder.onchange!=null) { recorder.onchange(); }
Here the change event should be fired when the content of the hidden input
field that is used to record the selection changes. However since the ajax
update on the onchange event is registered by AjaxFormComponentUpdatingBehavior
with jQuery, recorder.onchange will always be null.
The solution might be something like this:
$(recorder).change()
