Volker Weber commented on TOBAGO-287:
-------------------------------------
The tc:cell component (org.apache.myfaces.tobago.component.UICell) extends
org.apache.myfaces.tobago.component.UIPanel
which extends javax.faces.component.UIPanel,
both tobago components did not overwrite getRendered().
So i think the problem must be somwhere in the underlying jsf implementation,
which are you using?
Can you create a small example in plain jsf with the use of h:panel, to ensure
the problem is not there.
