Hi, and getting a org.hibernate.HibernateException: null index column for
collection: org.jbpm.graph.exe.ProcessInstance.instances EXception in the
moment I start a Taskinstance (TaskIntance.start() ).
The task instance has already the actor set, and everything seems to be well,
but, when I start it, it throws the exception.
Any Idea, or clue?
Thanks in advance
Fernando
The code:
protected void executeFirsTask(){
| JbpmContext ctx =
JbpmConfiguration.getInstance().createJbpmContext();
| try{
| List<TaskInstance> tasks =
ctx.getTaskMgmtSession().findTaskInstances(getUsername());
|
| if (tasks!=null && tasks.size() >0){
| TaskInstance ti =tasks.remove(0);
| ti.start(); //HERE Throws the ExceptioN!
| ti.end();
| ctx.save(ti);
| }
| }finally{
| ctx.close();
| }
| }
