I see... I fixed it following you recommendation. Thanks for prompt help.

Anyway, I'm still fighting with Ajax:
I want to show/hide a AjaxButton in dependence on whether
there is any value selected by the DropDownChoice.
I've AjaxButton on my form in the modal window hidden at the beginning:
musterButton.setOutputMarkupId(true);
musterButton.setVisible(false);
form.add(musterButton);
and in the handler of onUpdate event I'm trying to show it if selected
value is not null:
protected void onUpdate(AjaxRequestTarget target) {
...
musterButton.setVisible(pp.getMuster()!=null);
target.addComponent(musterButton);
}
But the button is not shown event if setVisible() is set to true.
What I'm missing now?
Thanks, Petr
