[jboss-user] [JBoss Seam] - Please help me! The page cannot change when jbpm is used.

Wed Nov 29 08:06:50 EST 2006

Hello.
I want to make the sample program of seam, and to change in pageflow.jpdl.xml the screen. 
The program moves well when pageflow.jpdl.xml is not used.
However, it is not possible to control with jbpm. 
Following information comes out though the error has not gone out. 

Could anyone advise,please?

It becomes deploy error if it describes it in component.xml.
