Thanks Igor, that was exactly what I needed to do. Could you tell me
what does target.addComponent() do? It tells Wicket which component
should be refreshed by the ajax request?

feedback.rendercomponent()???
i assume this add button is an ajax button? in that case you have to
add the feedback panel to the ajax target passed to you. there are
plenty of examples in wicket-examples.

Hello,
I have a FeedbackPanel, a TreeTable and an Add button. When I click on the
Add button, I check if there are any selected nodes in the tree. If there
are none, I want to display an error message in the FeedbackPanel. How to do
this?
The following doesn't work:
feedback.error("Select one node.");
i've also tried re-rendering it, but it also didn't work:
feedback.renderComponent();
What is the proper way to display the error message?
Regards,
Csaba
