 Hello,

 Recently started a wicket project and was making excellent progress till ran 
 into a problem with DropDownChoices. I am trying to get a DropDownChoice to 
 add a panel to a form when an option is selected. The DropDownChoice contains 
 a list of URI properties that each map to a different datatype. When a URI is 
 selected in the drop down the correct component (DateField, textField, 
 checkbox etc) needs to be added to the form to edit the property value. I am 
 using fragments to actually render the right component for the datatype (as 
 specified in the Bean editor example).

 My DropDownChoice does the following:

 protected boolean wantOnSelectionChangedNotifications() {
  return true;
 }

 protected void onSelectionChanged(final URI newSelection) {
  remove(dropdownChoice)
  add(new BagValueFormPanel(getComponentFactoryForURI(newSelection))
 }


 The BagValueFormPanel has a supporting model that adds edit components in a 
 ListView along with a + symbol to add more components.

 Unfortunately my list view panel does not get all the list items rendered. 
 When running the BagValueFormPanel unit test, I get the following debug tree:

 INFO  BaseWicketTester - path   form:panel      
 wicketclient.components.form.BagValueFormPanel  [[= null amp;amp;]]

 form:panel:valuesList:0:valueFragment:value:booleanOp   
 org.apache.wicket.markup.html.form.DropDownChoice       [amp;amp;]

 But when running the test for the dynamic DropDownChoice panel where the 
 selection is made to one of the list choices, I get the following tree 
 (form:panel:filterParameterPanel:valuesList is the matching component):

 INFO  BaseWicketTester - path   form    
 org.apache.wicket.markup.html.form.Form         []
 INFO  BaseWicketTester - path   form:panel      
 wicketclient.panels.search.PropertySelectComponent      []

 INFO  BaseWicketTester - path   form:panel:filterParameterPanel:addValue      
   org.apache.wicket.markup.html.form.SubmitLink   []

 Is this kind of dynamic addition of components possible on an 
 onSelectionChanged? If not I probably won't be able to add the panel in 
 earlier and delay the selection of the right Fragment to render the edit 
 control right?

 Cheers
