1. Re: TaskInstance and ProcessInstance not ending
kukeltje Dec 3, 2007 5:43 AM (in response to sowmyayellamilli)Can you make a minimal unittest with embedded processdefinition that demonstrates the problem?

3. Re: TaskInstance and ProcessInstance not ending
sowmyayellamilli Dec 4, 2007 7:47 AM (in response to sowmyayellamilli)Hi,
I tried the unit Test..... all were successful , but the thing is...
when i run the test case for Websale Example...even that processInstance didn't end
even after passing the end state...and the taskinstance before the end-state 'Fix web order data' didn't end (but it started)
(I mean ending when I see END_ column in JBPM_TASKINSTANCE & JBPM_PROCESSINSTANCE tables.... isn't?)
everything else was fine with it..
Please kindly help me out... -
4. Re: TaskInstance and ProcessInstance not ending
kukeltje Dec 4, 2007 9:32 AM (in response to sowmyayellamilli)??? You tried your own unittest? Or did you run the jbpm unit tests? What I asked was to *create* a unittest which demonstrated *your* problem, so I can try to reproduce.

sowmyayellamilli Dec 4, 2007 11:56 PM (in response to sowmyayellamilli)ok i'll get back to u with my unit test ...
meanwhile, i am not able to understand why websale also behaved the same way...websale unit test which i executed was like this:/* * JBoss, Home of Professional Open Source * Copyright 2005, JBoss Inc., and individual contributors as indicated * by the @authors tag.

i didn't change anything in the processdefinition or any of the classes that came with this example accept this test case...
i'll make a test case for my process definition....and get back to u... -
6. Re: TaskInstance and ProcessInstance not ending
sowmyayellamilli Dec 5, 2007 7:03 AM (in response to sowmyayellamilli)Hi,
I am really happy to say that my problem was solved....
the problem was with our database connections...
we were using a single connection pool for accessing two different schemas...and so we introduced 2 connection pools in place of that which solved the problem.....
there was NO PROBLEM with the JPDL or JBPM
anyway...thanx a lot for ur concern towards the problem
