Nestor Oviedo created DS-1196:
---------------------------------
Summary: Xmlworkflow multiple action configuration not deleting
claimed tasks
Key: DS-1196
URL: https://jira.duraspace.org/browse/DS-1196
Project: DSpace
Issue Type: Bug
Affects Versions: 1.8.2, 3.0
Reporter: Nestor Oviedo
There is a bug in the XmlWorkflowManager's processOutcome() method that relies
in not deleting the already processed CalimTask tuple from the DB. This happens
when there are two or more <action> in one <step> inside the xmlworkflow config.
For example, with the following config:
...
<step id="step1" role="role1" userSelectionMethod="claimaction">
<actions>
<action id="action1"/>
<action id="action2"/>
</actions>
</step>
...
When the claimaction is executed, it creates a ClaimedTask with info about the
user, the step and the action to be activated, which in this case would be the
first one: action1.
Whe action1 is completed, the XmlWorkflowManager::processOutcome() method is
executed to determine the next action (which will be action2) and then the
manager creates the ClaimedTask for this second action, but it never deletes
the old ClaimedTask.
As a simple workaround for this, I added the following code:
ClaimedTask task = ClaimedTask.findByWorkflowIdAndEPerson(c, wfi.getID(),
user.getID());
deleteClaimedTask(c, wfi, task);
before creating the new ClaimedTask (line 197 of XmlWorkflowManager).
Looking forward for comments
