Tag Library Supports Namespace

[Robert D. Morse]

I'm converting several MyFaces, Tomahawk 1.1.5 pages to MyFaces,  
Trinidad, Facelets and changing h: components to their respective tr:  
components.  I'm running into the following types of errors:

com.sun.facelets.tag.TagException: /xhtml/login/login.xhtml @38,27  
<tr:panelForm> Tag Library supports namespace: http:// 
myfaces.apache.org/trinidad, but no tag was defined for name: panelForm

Some other comments indicated this might be a problem with an earlier  
version of Trinidad, so I re-built from the latest in svn, and the  
errors persist.  Any suggestions?

Thanks.
