It could be that the jbpm timer clean up code is not synchronized where parts of jbpm are still hanging on to the completed timers.

[jBPM Users] - Re: Problem with timer

by sridhar18

Are you running your jbpm in a clustered jboss environment? This happens to me too. I get such exceptions on timers sometimes. I have a few timers in my jpdl. I think it happens when the activity the timer is on transitions to a different activity. For some reason, the other node in the cluster complains about the row not found for the timer. Although, the timers seem to do their job in my case. I'm also trying to find the root cause of this issue... View the original post : http://www.jboss.… [View More]

[jBPM Users] - [JBPM 4.1] Best practice to restart a task after shutdown /

by funkymac

What is the best-practice for restarting the task upon restart? (code sample would be great if you have it) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4268189#4268189 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4268189

[jBPM Users] - Character set for mail templates?

by markroy

jBPM 4.2 / JBoss / Windows XP I've got a string-type process variable that contains a unicode \u2019 (a right single quote aka apostrophe). I use that process variable in my mail template's 'text' and 'html' elements. When the mail arrives, the unicode character has been replaced with a '?' indicating that the character could not be mapped to the current character set, which apparently is Windows-1252. Is there a way to specify the character set? Other way to correct this problem? View the … [View More]

[jBPM Users] - jBPM Customization with EMF and DSL

by xspyro

Hi, I'm wondering how easy would it be to replace processdefinition.xml with some custom DSL. What I would like to do is to benefit from all nice features jBPM provides but instead of using xml as process definition use DSL (Domain Specific Language) to instrument PVM. I know that PVM is exactly about that (or maybe not) but the picture is kind of blurred when it comes to highlighting differences between PVM and jPDL. Next interesting question would be: How easy or difficult would be to … [View More]

[jBPM Users] - How to suspend Join Execution

by pradeep.gulla

Hi, I'm using JBPM4 with SQLServer. I've created a process XML such that it creates 4 parallel Tasks with Fork. These 4 tasks joins on completion(Approval) to initiate another new Task(single). My requirement is: If any task requests a rework, rest of all active tasks should gets terminated/ended. But when I'm trying to end any execution (by retrieving all tasks) I'm getting no session found. How to end these Tasks/executions ?? or End Join Execution ?? Thanks in Advance.
