in situations like this you have to wrap the panel in a webmarkupcontainer, call setoutputmarkupid(true) on it, and target that container in your ajax target.
that way the container will be drawn initially empty : <span id="container"></span> and when you make your panel visible it will contain the panel <span id="container"><span id="panel">....</span></span>

I want to change visibility attribute of a panel (containing other components) using Ajax.
The panel initially is hidden panel.setVisible( false ).
When user change selection in a radio group the panel should become visible.
I've tried to do something like that :
radio.add( new AjaxFormComponentUpdatingBehavior("onclick") {
protected void onUpdate(AjaxRequestTarget target) {
panel.setVisible( true );
target.addComponent(panel);
}
} );
But it don't work. Using the AJAX Debugger I could see that event is raised but it reports the following error:
ERROR: Component with id [[form1_panel]] a was not found while trying to perform markup update. Make sure you called component.setOutputMarkupId(true) on the component whose markup you are trying to update.
ERROR: error while processing response: [object Error].Object required
Obviuosly I used setOutputMarkupId(true) on panel.
Any idea why it don't work?
Thanks for helping.
