Hi Martin, thanks for the fast answer. The LeftToolbarPanel is a Panel which is added within a page. It contains a ListView with the two container markups. The information in the brackets is wrong.
I solved the issue just some minutes ago. I was adding a component to the ListView, but used the wrong id and not "toolbarcomponentleft". So everything is working fine. The Panel with the ListView can be replaced without any problems. :-) kind regards Tobias -----Ursprüngliche Nachricht----- Von: Martin Grigorov [mailto:mgrigo...@apache.org] Gesendet: Freitag, 18.

If it is really a ListView then the answer is that you cannot repaint repeater components with AjaxRequestTarget.
