In the process of migrating my code and processes from 3.0.2 to 3.1, I've encountered the following issue:
When deploying the following process
<process-definition name="Quick Test"> <start-state name="start"> <transition name="this was short" to="end" /> </start-state> <end-state name="end"/> </process-definition>
2006-02-14 17:49:06,667 DEBUG [org.jbpm.graph.node.NodeTypes] node 'page' will not be available. class 'org.jboss.seam.jbpm.Page' couldn't be loaded
This is a mere debug log statement. It only warns that the node type 'page' will definitely be unavailable as you are not using Seam. Nothing to worry about.
