[Ajax/TabbedPanel] Issue deleting all tabs + ajax-update
Hi,
The TabbedPanel internaly uses a Loop to render the tab-components.
During a normla GET request the Loop.onPopulate() method ensures that
all the loop-childs are removed before adding them again
to support a possible change of teh underlying Integer-model.
Loop.onPopulate()
@Override
protected final void onPopulate()
{
// Remove any previous loop contents
removeAll();
// Get number of iterations
final int iterations = getIterations();
if (iterations 0)
{
// Create LoopItems for each iteration
for (int iteration = 0; iteration iterations; iteration++)
{
// Create item for loop iteration
LoopItem item = newItem(iteration);
// Add and populate item
add(item);
populateItem(item);
}
}
}
The TabbedPanel creates the following LoopItem which access the
ITab-List directly.
return new LoopItem(tabIndex)
{
private static final long serialVersionUID = 1L;
@Override
protected void onComponentTag(ComponentTag tag){...}
@Override
public boolean isVisible() {
// direct access of the tab
return getTabs().get(tabIndex).isVisible();
}
};
The problem now is, if the tabs-list is modfied for example deleted, the
onPopulate() method NEEDs to be invoked before
the LoopItem.isVisible() the ensure that the old-Loop-childs (LoopItem)
are deleted.
This does not happen (Why?) if the TabbedPanel is added/updated in an
ajax-call, resulting in ArrayIndexOufBounds-Exception
in the LoopItem.isVisible() Method. (tabs.get(tabIndex)).
My workaround currently is to invoke the onPopulate() manually during
deletion (by beforeRender()).
((MarkupContainer)temporalTabs.get(tabs-container)).get(tabs).beforeRender();
Any Ideas, how to force the onPopulate() get called - maybe invoking
modelChanged() on some component???
Thanks
Jens

You can avoid this exception making sure to remove the tab from your panel
before the request cycle enter in RESPOND step.

Did you mean the the tab from the TabbedPanel or the whole TabbedPane from my page? - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: [Ajax/TabbedPanel] Issue deleting all tabs + ajax-update
ok i'm a little bit confused :-( I didt want to invoke 'tabs.remove()' during a onRender(), but during the onClick() method of by AjaxFallbackLink - like in your example. Using a normal Link the TabbedPanel doesnt throw the exception. Try your example with the AjaxTabbedPane and a AjaxFallbackLink. Then in onClick() you have to add the tp the the AjaxRequestTarget, which later leads to the ArrayIndexOutOfBoundsException.

I couldn't simulate, can you send the stack trace?
