Hi
I am testing the integration of jbpm 5 with jboss soa platform. So far, i downloaded soa-p-5.3.1.GA.zip and soa-p-5.3.1.GA-jbpm5.zip. Also, according with the instructions in the readme file of the soa-p jbpm 5 file, i downloaded the brms-p-5.3.1.GA-deployable.zip and deployed its content in the soa-p platform server
I am running the soa platform against an oracle database; so i modified all files to use that database.
Also, i created a esb project and deployed to the server. This esb project has a .bpmn file that represents my process definition; i can interact with this process via the esb project, that means, i can start a new instance of the process using the esb command available for that operation
But i cannot access the form that i defined for a human task inside the process. It is giving me this problem:
freemarker.core.InvalidReferenceException: Expression revRequestId is undefined on line 15, column 34 in LoanRevission.

But the variable in question (revRequestId) IS DEFINED in the bpmn file, and assigned to the task.
Another thing that i find weird is that, as i mentioned before, i can start instances of the process via the esb; but those instances does not show in the business-central console, or when i access the REST api of the business-central-server; i know that these instances exists, because i can see the tasks that are create for a user, and these tasks has an instance id associated with them; but the instances does not appear in the console or via the REST api, why ??
The other problem i am facing is that, i created a form to start the process, to test if it could be ran without the esb, but when i used this form to start an instance i get this error:

But, again, i can start a process instance via the deployed esb project; what is wrong with this
thanks a lot

I just tried Eclipse Kepler RC1 and JBoss Tools from http://download.jboss.org/jbosstools/builds/development/4.1.0.Beta1b.core... http://download.jboss.org/jbosstools/builds/development/4.1.0.Beta1b.core... . However, after doing a "Maven > Update Project", then I'm getting this stacktrace followed by a broken workspace. Broken means that when I restart Eclipse to use this workspace, then it crashes.
