[Trinidad 1.2] Render custom Facet on demand via ppr

[Elmar Kretzer]

Hi everyone,
 
i got a short question concerning the following scenario.
 
<tr:table ....>
    <tr:column>
        <tr:commandButton .../>
    </tr:column>
 
    <f:facet name ="customfacet" >
    <!-- 
        all the component stuff for rendering the details of this row 
    -->
    </f:facet>
</tr:table>
 
Is it possible to attach a Listener to the command Button to add a
custom DetailStamp function?
Or more generally speaking, is it possible to get a certain facet,
update its value and render it via ppr into a certain component?
 
Or is there any other way to add new content via ppr ( like an
tr:panelGroupLayout) to a position in the view root?
 
hope this question is not too stupid.... :-) 
 
(using Trinidad 1.2.6, Myfaces 1.2.2)
 
Thanks in advance!
