I'm using jboss-seam-1.0.1.GA with the special version of JBoss that goes with.

I defined a pageflow and everything worked fine until I added a description
tag inside a page tag:

<page name="CreateUserPage" view-id="/account/user.xhtml">
 <redirect/>
 <description>#{userMgr.description}</description>
 <transition name="create" to="EndPage" />
 <transition name="cancel" to="homePage" />
</page>

A java.lang.NoSuchMethodError Exception occurs in the prepareBackswitch method of org.jboss.seam.core.Manager in line 867 where the description is set (see stacktrace below):

conversation.setDescription( page.getDescription() );

Where page is org.jbpm.pageflow.Page

I even replaced the description by a hardcoded string (to make sure there was nothing wrong with my bean) but I get the same exception.

Any idea?

Thanks

Richard
