[jBPM Users] - Unit test succeeds but process does not properly run when de
by sebastian.s
Good morning folks!
Sorry but it's me pestering the forum with my questions again. ;) I tried to implement a kind of 4-eyes-approval where the decisions of the 2 people can be made concurrently. I had trouble with this process because when I tried to start a new instance in the jbpm-console I did not see a new instance. Furthermore when I tried to view the 2 users' tasklists to check if the tasks had been created I got an exception:
| org.jboss.resteasy.spi.UnhandledException: org.hibernate.LazyInitializationException: could not initialize proxy - no Session
|
I thought this was a bug already reported but I don't manage to find the matching posts and the matching issue in JIRA anymore. I was sure there was a thing partly related to the engine and partly related to the console. At first I thought it was just an issue with the console because I made a unit test for the process and it passed. Afterwards I was using the API of the Process Engine instance used by the console to go through the process without using the console and it did not work. Buit when the unit test passes it should run on the server as well (in my case Tomcat), or not?
Process definition and unit test follow. I am using jBPM 4.1 running on Tomcat on a Windows Server System.

I have done all the relevant configuration, however, I am not able to login to the console.
Please help.
Thanks !

[jBPM Users] - Re: jbpm 4.1 - execution not waiting for Task Form inputs
by makarandk502
Hi,
Even in my case, its reaching at "review" task. print statements like "List is[Task(review)]" But in "review" task, we have associated a form which can be viewed in jbpm console. Ideally we should view the form and once we enter "submit" , it should proceed further. Basically it is not waiting for user inputs in taskform
But I am not able to see the form in jbpm console and it is deleting process instance. I am attaching jbpm test case result below.
