ExclusiveGatewayExpression - Can I use a return of a Spring Bean method call?

[edufrazao]

I want to retrieve some information used in user tasks on a expression in a ExclusiveGateway.

For now, I'm using a ScriptTask to call a local service (A Spring Bean), and set the return as a Process Variable.
<javascript>
var accepted = vFormService.getFormValueAsString(execution.processInstanceId, 'formKey',  'accepted');
execution.setVariable("accepted", accepted);
</javascript>
I use a local form service to handle this data, a custom implementation. I don't use the default FormService from Activiti.

This approach works, but it will be a simplest solution, to call this service from the ExclusiveGateway, like:

<javascript>
#{vFormService.getFormValueAsString(execution.processInstanceId, 'formKey',  'accepted') == 'true'}
</javascript>

I try, but the service is never called, and the default flow is always used.

Hmmm, that should work in theory (if the vFormService is a Spring bean). Tried changing to $ instead of # (its a long shot)? Does it work if you just call it from a service task expression

Yes, vFormService is a SpringBean. I've named it with a "v" prefix, because formService is also a Bean (Activiti FormService).
Using the same call in a Service Task works, and changing # to $ does not solve the problem. The method is never called.

Hmmm  okay, can you post the xml of your process so we can try it ourself?
