Notification & workflow

Hi,

I'm working on a password reset mechanism through workflow.
When the task 'pwreset' is called I execute a class that sets a user
property (pwreset) to true and then goes to the "activate" state.

Part of the workflow:
...
    <userTask id="active" name="Active"/>
    <sequenceFlow id="flow7" sourceRef="active" targetRef="activeGw"/>
    <exclusiveGateway id="activeGw"/>
...
    <sequenceFlow id="active2PasswordReset" sourceRef="activeGw"
targetRef="initPWreset">
      <conditionExpression xsi:type="tFormalExpression">${task ==
'pwreset'}</conditionExpression>
    </sequenceFlow>
...
  <serviceTask id="initPWreset" name="Initialize password reset"
activiti:class="my.package.InitPWReset"/>
    <sequenceFlow id="PWRflow1" sourceRef="initPWreset"
targetRef="activate"/>
...
 <userTask id="activate" name="Activate"/>
...

I have notifications on the activate state which depend on the pwreset
property being true/false. I get notifications when I do a normal user
activation (with token).
However when I go through the pwreset flow I should get a notification (the
user object has pwreset=true and is in the "activate" state) but I see
there's no notification task.
Where are these notification tasks generated? Or do I have to create them
in my InitPWReset class?

best regards

Bob

NotificationTask objects are generated by the NotificationManager that 
is normally invoked after workflow execution has finished: the actual 
sequence is (check UserController.create() for an example):

1. workflow (WorkflowAdapter)
2. propagation (PropagationManager)
3. notification (NotificationManager)

Regards.
