Hi everybody .
I have a problem to go to next task-node with jbpm in a web application by
using struts.
i did a small process like this:
anonymous wrote : start
| task1
| task2
| end
On my first bean in strut, i deploy process and i go to the first task.
But when i write this in order to go to the next task:
anonymous wrote :
| TaskMgmtSession taskMgmtSession = jbpmContext.getTaskMgmtSession();
|
| TaskInstance taskInstance =
taskMgmtSession.loadTaskInstance(1);
| taskInstance.setActorId(jbpmContext.getActorId());
| taskInstance.start();
|
| Token token = graphSession.loadToken(1);
| Transition transition=null;
| String transitionName=null;
|
| if
(token.getNode().getLeavingTransitions().isEmpty() == false) {
| Iterator availableTransitionsIterator =
token.getNode().getLeavingTransitions().iterator();
| while
(availableTransitionsIterator.hasNext()) {
| transition = (Transition)
availableTransitionsIterator.next();
| }
|
transitionName=transition.getName();
| }
|
| token.signal(transitionName);
| ProcessInstance processInstance =
token.getProcessInstance();
|
| jbpmContext.save(processInstance);
|
there are an error :
anonymous wrote :
| Integrity constraint violation - no parent FK_TASKINST_TASK table:
JBPM_TASK in statement [insert into JBPM_TASKINSTANCE (NAME_, DESCRIPTION_,
ACTORID_, CREATE_, START_, END_, DUEDATE_, PRIORITY_, ISCANCELLED_,

SWIMLANINSTANCE_, TASKMGMTINSTANCE_, CLASS_, ID_) values (?, ?, ?, ?, ?, ?, ?,
?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 'T', null)]
|
