Jbpm action is called infinitly

[gewuerzgurke]

Hello everyone,

I've got a problem while developing a jbpm business process that has to wait until a specified time and execute an action.
Everything works as expected while not using outjection on a variable. If outjection is activated through the @Out annotation
the action method gets called infinitly.

----- The Process ------

<?xml version="1.0" encoding="UTF-8"?>
<process-definition  xmlns="urn:jbpm.org:jpdl-3.2"  name="sellingProcess">
<start-state name="new selling">
     <transition to="wait auction"></transition>
</start-state>
<state name="wait auction">
        <timer name="waitAuctionTimer" duedate="1 minute" transition="interuptWaitAuction">               
          <action expression="#{sellingManager.startAuctioning}"/>                              
     </timer>
     <transition to="wait selling" name="interuptWaitAuction"/>
     <transition to="end invalid selling" name="interuptFailedWaitAuction"></transition>
</state>

<state name="wait selling">
</state>
     
<end-state name="end invalid selling"/>
 

----- The Component -----

@Name("sellingManager")
@AutoCreate
public class SellingManagerBean implements SellingManager {
//     @Out(scope=ScopeType.BUSINESS_PROCESS, required=false)
     @In(scope=ScopeType.BUSINESS_PROCESS, required=false)
     Selling selling;
     
     @Transactional
     public String startAuctioning() {
          if( selling.getEbayItemId() == null && selling.getEbayItemLink() == null ) {
               String itemId = ebayDriver.addItem(selling);
               selling.setEbayItemId(itemId);
               selling.setEbayItemLink(buildEbayItemUrl(itemId, ebayDriver.getEbayModuleConfiguration().isProduction()));
               return itemId;
          }
          return null;
     }
}

If @Out(scope=ScopeType.BUSINESS_PROCESS, required=false) is active, the startAuctioning method is called infinitly.

I'm using Seam 2.2.0 GA, Jboss5 and Jbpm 3.2.6SP1

Anyone an idea?

I believe there is a bug with outjection on business process scope with seam.
We had to implement a workaround in our application for this behaviour.
I can't remember what the bug was, or if it is applicable for your situation, but
basically what we are doing is outjecting the value directly to the business context.

taskInstance.getProcessInstance().getContextInstance().set("selling",selling)

Now you can from your java or xhtml page inject and use the value either with

@In(scope=ScopeType.BUSINESS_PROCESS)
 private Selling selling;
//or directly from EL #{selling}

Hope this helps.
