Dear Jakob,
Thanks for your reply !
After investigation, my problematic pages where only pages with an
inputFileUpload components.
For these pages I added an exception for my filter in the web.xml :
<filter>
<filter-name>localLanguageFilter</filter-name>
<init-param>
<param-name>EXCEPTION_URL_0</param-name>
<param-value>/shortcuts/contacts.faces</param-value>
</init-param>
<filter-class>
ec.ep.eo.eoweb.filter.LocalLanguageFilter
</filter-class>
</filter>
And then in my filter I get this exception and user filterChan.doFilter
For all other pages I use request.getRequestDispatcher(uri).forward(request,
response)
I found some interesting help also here :

Marc
