Hi, I have a problem using JBpm with Seam. I modeled a process with nodes and binded actions to these nodes. But the injection of business process variables or processInstance in Seam component does not work when running these actions. I don't have the problem if the token did not go through a task-node before (ie a business process with no human action). I guess it deals with a context problem, but I can't understand what the problem exactly is. For example, I modeled my node this way : <node name="Acceptation"> | <transition to="End" /> | <action expression="#{demandeAbsenceAction.demandeAcceptee}" /> | </node> I have a first Seam component (conversation scope) which creates the process instance this way : @org.jboss.seam.annotations.bpm.CreateProcess(definition = "validationDemandeAbsence") | @org.jboss.seam.annotations.End | public void valider() | {} It also outjects idDemandeAbsence variable in the business process : @org.jboss.seam.annotations.Out(required = false, scope = org.jboss.seam.ScopeType.BUSINESS_PROCESS) | protected java.lang.Long idDemandeAbsence; I had a look in the JBPM tables and this outjection works well. I have another Seam component (conversation scope too) which contains methods binded to JPDL nodes. It injects processInstance and idDemandeAbsence variables this way : @org.jboss.seam.annotations.In(create = true) | protected org.jbpm.graph.exe.ProcessInstance processInstance; | | @org.jboss.seam.annotations.In(value = "idDemandeAbsence", scope = org.jboss.seam.ScopeType.BUSINESS_PROCESS) | protected java.lang.Long idDemandeAbsence; And of course it declares the action method binded to JPDL node (no annotation on this method, should there be some ?) : public void demandeAcceptee() | {} But idDemandeAbsence and processInstance variables are alway null. Do I use JBpm and Seam the right way ? I work on this problem for several days, so any help will be greatly appreciated ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4089601#...
