[jboss-user] [JBoss Seam] - How to use a Seam component in swimlane assignment

Hi, My application uses a JBPM business process and I need to assign tasks on runtime. To do this I made a Seam component and I call it in the swimlane assignment expression. To be more precise, the task is defined as following : <task-node name="validation"> | <task swimlane="valideurs"></task> | <transition to="acceptation" name="ok"></transition> | <transition to="refus" name="nok"></transition> | </task-node> And the swimlane is defined as following : <swimlane name="valideurs"> | <assignment expression="#{assignmentHandler.assignByRole('USAGE')}"></assignment> | </swimlane> The assignByRole method of my assignmentHandler component returns String[] (not sure it is correct, but I could not find any example). But when I create a process instance, I have the following error : 11:55:04,241 ERROR [STDERR] Caused by: org.jbpm.identity.assignment.ExpressionAssignmentException: couldn't resolve assignment expression '#{assignmentHandler.assignByRole('USAGE')}' | 11:55:04,241 ERROR [STDERR] at org.jbpm.identity.assignment.ExpressionAssignmentHandler.assign(ExpressionAssignmentHandler.java:97) | 11:55:04,241 ERROR [STDERR] at org.jboss.seam.bpm.SeamUserCodeInterceptor$2.process(SeamUserCodeInterceptor.java:102) | 11:55:04,241 ERROR [STDERR] at org.jboss.seam.bpm.SeamUserCodeInterceptor$ContextualCall.run(SeamUserCodeInterceptor.java:33) | 11:55:04,241 ERROR [STDERR] at org.jboss.seam.bpm.SeamUserCodeInterceptor.executeAssignment(SeamUserCodeInterceptor.java:96) | 11:55:04,241 ERROR [STDERR] at org.jbpm.taskmgmt.exe.TaskMgmtInstance.performAssignmentDelegation(TaskMgmtInstance.java:226) | 11:55:04,241 ERROR [STDERR] at org.jbpm.taskmgmt.exe.TaskMgmtInstance.performAssignment(TaskMgmtInstance.java:201) | 11:55:04,241 ERROR [STDERR] ... 171 more | 11:55:04,241 ERROR [STDERR] Caused by: org.jbpm.identity.assignment.ExpressionAssignmentException: couldn't interpret first term in expression '#{assignmentHandler.assignByRole('USAGE')}' | 11:55:04,241 ERROR [STDERR] at org.jbpm.identity.assignment.ExpressionAssignmentHandler.resolveFirstTerm(ExpressionAssignmentHandler.java:155) | 11:55:04,241 ERROR [STDERR] at org.jbpm.identity.assignment.ExpressionAssignmentHandler.assign(ExpressionAssignmentHandler.java:75) | 11:55:04,241 ERROR [STDERR] ... 176 more So it looks like you can not use EL expressions in swimlane assignment ... Anyone has an idea how I should do this ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4110136#...
