p:commandbutton update does not work

Question

I have searched through forums and am aware of how id-generation of HTML-DOM-Elements work with NamingContainers and without them. Nonetheless, in this code i try to put a commandbutton in one side of the page, that should trigger an update of the other side of the page.

The 'viewWorkbenchButton' fires its action properly and the backend-data is fine. But :wbManageForm:wbMgmtPanel is not updated.

I already tried to update different components ( :wbManageForm , :wbManageForm:tabText , :wbManageForm:tabView:treetable ) but none of them was updated...

I am using Primefaces 3.5.

What am i missing here? Thanks a lot in advance!

Answer 1

Try using action instead of actionListener . Also, update only the wbmanageForm . If that doesn't work, try updating the component with your bean method.

You can do that by adding this to the end of your method: RequestContext.getCurrentInstance().update("wbManageForm");
