Please Help
Hi,
I made a processdef like this:
<process-definition name="Processus qualité2"+
<start-state name="start">
transition name="To_analyse_transition' to='Task_byPM"
</start-state>
<task-node name="Task_byPM">
and it's well deployed,
then when i execute the code:
______________________
JbpmSession jbpmSession = jbpmSessionFactory.openJbpmSession();
//GraphSession graphSession = jbpmSession.getGraphSession();
jbpmSession.beginTransaction();
ProcessDefinition processDefinition = jbpmSession.getGraphSession().findLatestProcessDefinition(requestParam.getRequestType());
ProcessInstance processInstance = new ProcessInstance(processDefinition);
// ContextInstance: process variables :)
ContextInstance contextInstance = processInstance.getContextInstance();
contextInstance.setVariable("Commentaire de l'utilisateur final", requestParam.getComment());
contextInstance.setVariable("ProjectManager", requestParam.getProjectManagerID());
contextInstance.setVariable("Nom du projet", requestParam.getProjectName());
contextInstance.setVariable("Type requête", requestParam.getRequestType());
processInstance.signal("To_analyse_transition");
jbpmSession .getGraphSession().saveProcessInstance(processInstance);
jbpmSession.commitTransaction();
jbpmSession.close();
i have the following error :(
java.lang.NullPointerException
