here's the background to my problem:
I have the following process definition
START----->TASK-NODE----->NODE(with custom action)------>END
here's the code to the custom action class:
| public void execute(ExecutionContext executionContext) throws Exception {
| //check if TEST mode is one
| ContextInstance contextInstance =
executionContext.getContextInstance();
| String testMode =
(String)contextInstance.getTransientVariable(JbpmConstants.TEST_KEY);
|
| //TEST MODE OFF
| if(null == testMode) {
| executionContext.leaveNode(JbpmConstants.TRANSITION_GO_NEXT);
| }
| //TEST MODE ON
| else {
|
| //set node name in as both key and value
| contextInstance.setTransientVariable(JbpmConstants.NODE_UPDATE,
JbpmConstants.NODE_UPDATE);
| String exceptionFlag =
(String)contextInstance.getTransientVariable(JbpmConstants.TEST_UPDATE_EXCEPTION);
| if(null == exceptionFlag) {
| //no exception
|
executionContext.leaveNode(JbpmConstants.TRANSITION_GO_NEXT);
| }
| else {
| throw new Exception(JbpmConstants.TEST_UPDATE_EXCEPTION);
//test for exception
| }
| }
| }
| }
|
and here is the code for my junit test:
| .
| .
| .
| _token.signal();
| _activatedNode =
(String)_token.getProcessInstance().getContextInstance().getTransientVariable(JbpmConstants.NODE_UPDATE);
| assertNotNull(_activatedNode);
| assertEquals(_activatedNode, JbpmConstants.NODE_UPDATE);
|
The idea is I want to test to make sure my custom-node is activated after
signalling from the TASK-NODE, and I'm using transient variables to test this
result. So far this has work with other workflows where a signal of a task node
leads to another task node (i.e. not end state). However once I signal from a
task-node into an eventual end-state, I find that all my transient variables
are gone.
I've also tried to print out all variables (transient and non-transient) after
the signal() call, but both maps are null.
Does anyone know why this is so?
