You are getting the error because Trinidad is not yet compatible with partial state saving in JSF 2.0. Since partial state saving is enabled by default when Facelets are used, you need to explicitly disable it. Add the following context parameter in web.xml: <context-param> <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name> <param-value>false</param-value> </context-param> Hope this helps, Max Starets On 1/25/2011 5:23 PM, Catherine Rocchio wrote: > 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?
