jBPM to ESB mapping

[kadlecp]

Hello,

I have child tokens in my business process execution. I've encountered "strange" behaviour. My sample esb service is called in the scope of child token. JBPM job that is created by esb JBpmCallbackService puts output variables from that sample esb service to the scope of root token as well, and not only to the scope of child token.

I do not understand why there are these lines in org.jboss.soa.esb.services.jbpm.cmd.AsyncProcessSignal.AsyncSignalAction

 final int variableCount = Integer.parseInt((String)contextInstance.getVariableLocally(ESB_ASYNC_SIGNAL_VARIABLE_COUNT, token)) ;
 for(int count = 0 ; count < variableCount ; count++)
 {
 final String name = (String)contextInstance.getVariableLocally(ESB_ASYNC_SIGNAL_VARIABLE_NAMES + count, token) ;
 final Object value = contextInstance.getVariableLocally(name, token) ;
 // HERE YOU PUT VARIABLES TO SCOPE OF ROOT TOKEN
 contextInstance.setVariable(name, value) ;
 }

When I delete these lines, I achieve desired (from my point of view) behaviour, not to put output variables to the scope of root token.

I deleted this line in org.jboss.soa.esb.services.jbpm.cmd.AsyncProcessSignal.createSignalJob as well

setVariable(contextInstance, token, ESB_ASYNC_SIGNAL_VARIABLE_NAMES + (count++), name) ;

Regards
Pavel

That is correct, they are currently accessible to all tokens within the process.

So that they can be made available to all tokens within the process.

Adding a scope for this would be a good idea.

Shall I create feature request? I would appreciate that possibility.

Thanks
