Thank you very much for your response,
On your advice I wrote an PahseListener but it doesn't work. I don't know if
it is a config failure or not.
The problem is I think that in my web.xml the Extension-filter is set to
false.
<context-param>
<param-name>org.apache.myfaces.CHECK_EXTENSIONS_FILTER</param-name>
<param-value>false</param-value>
</context-param>
thats because I use the tomahawk-bridge in my portlet and for these the
Extension-filter must be shutdown.
is these the reason???
in my faces-config.xml I did the following to run the phaseListener:
<lifecycle>
<phase-listener>main.org.jboss.portlet.milestone.portlet.phaselistener.ImagePhaseListener</phase-listener>
</lifecycle>
thanks,
Omid
