Hi there,
We are new to using JSF/Facelets etc (of course!) and we are having a very
frustrating problem
With: MyFaces 2.0, Trinidad 2.0 Alpha, and Facelets.
Generally, my question is this:
How should the ViewHandler be defined for Facelets to work with Trinidad tags?
An entry in web.xml only? I see all sorts of conflicting and/or old
information out there. Specifically, SHOULD I define an entry for
ALTERNATE_VIEW_HANDLER and what should that be set to? I don't have a
com.sun.facelets library anywhere in my setup.. (should I? Where should I get
that from?) - and I've also seen mention of this class file -
org.apache.myfaces.trinidadinternal.facelets.TrinidadFaceletViewHandler - but
it doesn't exist either.
Specifically, I have a VERY basic xhtml page set up with some Trinidad tags -
and a backing bean. The same old login page that everyone in the world uses -
and I have navigation set to move to another page when I hit at button - and
the rules are all defined.
No matter WHAT I do - I constantly get this error upon hitting any sort of
button/widget that implies navigation...
