Make changes on component using ViewHandler

Hi,

I declared a viewhandler that goes through all components and childrens
components checking for the attribute "permission", which is set on some
using f:attribute. If it is found I do some stuff finding out if this
component should be rendered. If no, i setRendered(false) on the component.

However, the component still gets rendered and I do not know why? Does
anybody know why the setting of rendered to false does not have any impact?

Best regards

Thank you very much.

But just to recap that thread to see that I am not missinterpreting. It is
not possible to change components found in the ViewRoot using a ViewHandler
or PhaseListener. It is however possible to do this by using a custom
UIViewRoot?

Best regards

You find the components after the renderer phase built by
encodeChildren. Search for the topic " Change visibility dynamically"
and you'll find a solution...
