I dont know if this is already possible; if so, I'd appreciate advice.
More and more we find we have a need for "task properties" that are definable
in the Task element in the processdefinition.xml file and retrievable from a
Task object. For instance, it would be useful to put:
| <task-node name="Record Officer - Check Expiration">
| <task name="Record Officer - Check Expiration" blocking="true">
| <assignment class="MyAssignmentClass">
| <currentStep>Record Officer - Check Expiration</currentStep>
| <Role>Record Officer</Role>
| </assignment>
| <properties class="MyPropertiesClass"
| <managerRole>Manager</managerRole>
| <maxDurationDays>5</maxDurationDays>
| <expirationEmail>[EMAIL PROTECTED]</expirationEmail>
| <helpPhone>555-555-5555</helpPhone>
| </properties>
| </task>
| <transition name="Done" to="Decide if Record Officer
Complete"></transition>
| </task-node>
|
The <properties> element is the proposed new feature.
This would then allow:
| TaskInstance taskinst = ...
|
| MyPropertiesClass taskProps =
| (MyPropertiesClass) taskinst.getTask().getProperties();
|
| if (elapsedDays > taskProps.maxDurationDays)
| {
| sendEmail(taskProps.expirationEmail, "Overdue!");
| // etc.
| }
|
Essentially, JBPM would use reflection to set the members of the
MyPropertiesClass object which would be stored in an Object member of the Task
and retrieved with the getter "Task.getProperties()", similar to other
delegation object initializations. It would be required that MyPropertiesClass
be serializable for storing by Hibernate. Perhaps a HashMap could be a
default "properties" object.
Is anyone interested in such a feature, or is it already possible?
