Multi-instance task variable use

Question asked by stephenl on Jan 20, 2017

have an Activiti workflow that creates multiple (parallel) user tasks for an authorisation task (assigns each one to a group based on one element of a list).

<userTask id="authReview" name="Authorisation Review" activiti:candidateGroups="${assignee}" activiti:formKey="rowf:authReviewTask">
        ${assignee} Data Access request for approval.

    <!-- One instance of this user task for each group that needs to authorise the request -->
    <multiInstanceLoopCharacteristics isSequential="false"
        activiti:collection="${rowf_reviewers}" activiti:elementVariable="assignee" >


As the ${assignee} variable is used to allocate the task to the correct group (after being read from the ${rowf_reviewers} list, is there any way to use ${assignee} to add to the task description? The task description is currently set by the documentation tag which seems to work fine but nothing is read from ${assignee}. I think this may be to do with a timing issue with the population of ${assignee} as "may" be populated before the documentation gets evaluated.

Any assistance on how to get ${assignee} into the description would be appreciated.
