However, I do not know, why ui:repeat does not view the datas of my list whereas c:forEach does:
when clicking the button, I update my "panel" via ajax. However, only "output_text" shows me, the list. Ui:repeat shows nothing after ajax update (I guess it does not iterate through the list). C:ForEach iterate through the list and shows me the listdata, but only when clicking the button twice! What is wrong?
