Hi:

I am working on a UI for JBPM. When starting a ProcessInstance, I inspect the startTaskInstance for any variables that need to be supplied. However, when saving the process instance, I receive the following hibernate exception:

instance not of expected entity type: org.jbpm.context.exe.VariableInstance

Here is the code I am using to get the startTaskInstance:

TaskInstance taskInstance = processInstance.getTaskMgmtInstance().createStartTaskInstance();

I then use the taskController to gain access to the variables if they exist. This is used to construct the UI.

TaskController taskController = taskInstance.getTask().getTaskController();

if (taskController != null) {
List variableAccesses = taskController.getVariableAccesses();
Iterator iterator = variableAccesses.iterator();

while (iterator.hasNext()) {
VariableAccess variableAccess = (VariableAccess) iterator.next();
String mappedName = variableAccess.getMappedName();
String value = (String) taskInstance.getVariable(mappedName);
?
}
}

Does anyone know why I am seeing this exception and can you recommend a solution?

Thanks,

Jeff
