RequestParamServltFilter Bug (or Premature Conversation Tag WIKI Entry)

["Neuman, Ben J., A&M IRM" <bj...@hq.afis.osd.mil>]

First, my apologies for the premature WIKI entry concerning the Conversation
Tag. I'll be more discerning about my entries in the future.

I found that certain components broke the app when I registered the
RequestParameterServletFilter. Order of the filters does not seem to make a
difference. The following Exception is thrown when I navigate to a page
containing a <t:inputCalendar> or <t:inputDate> tag. By enabling
StreamingAddResource, the exception goes away (however, the components have
a screwy layout until I additionally implement the <t:document*> tags.

Stack Trace: using MyFaces 1.1.4 and Tomahawk/Sandbox 1.1.4

Oh - that was no problem. I just didnt know how to reach you so I
thought I try through the wiki page itself.
:-)

I use the conversationTag with the "old" DefaultAddResource and didnt
have your problem - and I use the inputCalendar, etc stuff.
Could you please post (or send me) your web.xml.
It must have something to do with the filter mapping.

As a hint - In our application we have a mapping like (in this order):
FacesExtensions, RequestParameterFilter, ConversationFilter - all mapped
to "/path/*"
Our Faces Servlet is mapped to "*.faces"
So a typical url looks like /path/MyFacesPage.faces

Thanks!
Ciao,
Mario
