Hi :
I got a db constrain failure when call executionService.signalExecutionById(executionId) for the "check_id" state node as shown below.
================================
<?xml version="1.0" encoding="UTF-8"?>
<process name="SubDocument" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl">

</event-listener>
</on>
</end>
</process>
======================
The exception is listed below:

===============================
But if I remove the "check_id" state node and make the start node's transition directly go to the sub-process, everything goes fine.
Can someone help me about this one? Thanks a lot in advance.

[jBPM] - jBPM 4.3 Spring bean as event listener

I have followed the recommendations in the developer's guide for doing Spring integration with jBPM 4.3. My application deploys to JBoss 5, and the server starts cleanly.
Here's my issue: I want my processes to be able to use Spring beans for event listeners. The relevant process code is:
> <process name="speechrec" ...>
> <on event="start">
> <event-listener expr="#{processListener}" >
> <field name="eventType">
> <string value="start"/>
> </field>
> </event-listener>
> </on>
The bean id "processListener" is defined in my Spring config, and the expression #{processListener} is evaluated to the correct class name, but the class is instantiated by jBPM instead of Spring. So the bean's Spring properties are not injected, so of course I get NPE's whenever they are used. I was hoping the "expr" attribute would behave like Spring's "ref" attribute and make use of an existing bean if there is one.
Is there any way to get what I want? Does it mean that only jBPM beans can be used as event listeners?

[JBoss Portal] - Issue with Subscription mode "E-Mail validation and admin approval"

Hi. I'm testing JBoss Portal in order to check whether it's suitable for a project we are planning to do.
I'm having a problem trying to configure the user registration with subscription mode "E-Mail validation and admin approval". The jBPM workflow was apparently stucked (in fact it was pending) and I couldn't found an easy way to check why. After a couple of minutes of testing I found my email account was incorrectly configured and that explained why there was an error about this in the server's log. Instead of reconfiguring the server I directly browsed to the email verification URL (someone posted in a blog what the format of that URL was) and a page showing the validation success message came along. After that, I logged in as a portal admin and browsed to the User Management section... then I clicked the "Show pending registrations" link but unfortunately the list was empty. I tryied to find out for a couple of hours why this happened but I was unable to discover a solution. Any ideas?
Info: JBoss Portal 2.7.2 bundled with JBoss AS 4.2.3, Ubuntu Desktop 9.04, Java SE 1.6.0_18-b07
