this is caused by

I checked seam source code, Page is a subclass of Node. I double-checked that
we are using jbpm3.1.1. "org/jbpm/graph/action/action.types.xml" is in the
jbpm3.1.1.jar and it does specify Page in it. I tried to reference
action.types.xml in jbpm.cfg.xml file according to the comments in Page class.
It does not help.
Does you have any suggestions? Gavin. Hopefully this extra info could be
helpful. I will post a JIRA issue later.
