Hello:
I used jbpm 3.1.3 in my project , I writed a method of a business service class like this:

@Transactional(readOnly = true)
public List listAllProcessDefinition() {
return (List) jbpmTemplate.execute(new JbpmCallback() {
public Object doInJbpm(JbpmContext jbpmContext)
throws JbpmException {
return jbpmContext.getGraphSession()
.findAllProcessDefinitions();
}
});
}
there is no process definition record in table "JBPM_PROCESSDEFINITION" when the project is initialized,when I used mysql database, the method "findAllProcessDefinitions()" had been invoke fine,but when I change to oracle database,it will throw a IndexOutOfBoundsException ,it like this:java.lang.IndexOutOfBoundsException: Index: 0, Size: 0.
when I deploy a new process definition , this exception will disappeare,I have no good ideal about it ,can you help me?
