Hi,
I am using JBPM 5.2 with MySql & Tomcat 6 in windows 7.
I have created 3 tomcat instances (T1, T2 & T3)
T1: deployed gunor & jbpm console in this tomcat
T2: deployed human task service war (I converted task service 5.2 module into a war file)
T3. My web application which will handles process & human tasks related requests.
I have created a simple workflow with 2 human task nodes.
I am getting the below mentioned exception while executing these steps.
1. Start the process (it will create a task record in Task table for my first human task)
2. Read the processInstance by using knowledgeSession.getProcess(id)
3. Complete the first human task. (here I am getting the actual exception)
4. After I get the exception, the process continued and there are 2 task records created in Task table for the second human task.
If I skip the 2nd step and execute the steps 1,3 & 4, I am not getting this exception and it is working fine.
Observations:
When we read the processInstance by using knowledgeSession.getProcess(id) method, internally it is updating the processInstanceInfo table by increasing OPTLOCK value. After this if we complete the task, we are getting the below exception.
Please help me out on solving this issue.
