Component binding question

["Pfau, Oliver" <ol...@siemens.com>]

Hi,
 
I use as portlet communication a component binding as trigger to refresh
a details portlets content. There's a rendered=false component in my
details portlet and in the get/set of the component binding a portlet
session attribute will be read. It work when I choose the items from the
navigation portlet and they are shown in the details portlet. But when I
do some action in the details portlet, the component binding get/set are
no more invoked. So my question: in which cases are the component
binding methods are not invoked ?
 
Thanks,
Oliver
