I18n support for userTask's documentation tag

[limcheekin]

Hi there,

May I know userTask's documentation tag support internationalization such as a message bundle define for each locale?

Please advice. Thanks.

No, not yet. Spring Surf does have everything baked into it to handle it … but it is not yet implemented in our webapps.

Thanks for quick response. Given approveVacation.description defined in the messages.properties, will activiti engine pick up itself if I defined the following userTask in my bpmn20.xml file:

  <userTask id="handleVacationRequest" activiti:formKey="/vacationRequest/approval"
   name="Handle Vacation Request">
   <documentation>approveVacation.description</documentation>
   <potentialOwner>
    <resourceAssignmentExpression>
     <formalExpression>management</formalExpression>
    </resourceAssignmentExpression>
   </potentialOwner>
  </userTask>

Please advice.

Thanks,

Hi Lim, internatibnalization is not supported at this moment.
Are you using your own forms technology? If so, you could probably look up the key before it is displayed.

Hi Joram,

Thanks for writing.

Yes, I did put some thought on this. I have no problem to look up the key. But how do I access to variable username given the following bpmn20.xml:

<userTask id="initiateVacationRequest" activiti:formKey="/vacationRequest/create" name="Initiate Vacation Request">
  <documentation>Vacation request by ${username}</documentation>
………

Hm… The solution seems like I need to store the username in task variable and resolve it myself when my application detect ${username} in the documentation tag. Do you have better suggestion?

Lastly, is this feature (internationalization support) is in the Activiti roadmap?

Mmm.. if you do a task.getDescription, doesnt it resolve the variables automatically?

Internationalisation is not directly on our roadmap (ie first 4-6 months), since we first want to stabilize and build out the engine features before going full speed ahead with the UI's.

Given bpmn20.xml:

   name="Handle Vacation Request">
   <documentation>approveVacation.description</documentation>
   <potentialOwner>
    <resourceAssignmentExpression>
     <formalExpression>management</formalExpression>
    </resourceAssignmentExpression>
   </potentialOwner>
  </userTask>

and message.properties:

approveVacation.description=Vacation request by ${username}

Will task.getDescription() resolve the ${username} variable automatically?

Ah, now I understand your question…. but no, it won't resolve it.
It will resolve everything before returning the value from task.getDescription.

However, you can use the ExpressionManager class to create an Expression from the value you get back from your messages.properties. That expressio n then needs the execution from your task to be evaluated. The ExpressionManager is normally available on the configuration (but maybe you need to cast).

Thanks, seems like working with ExpressionManager is the way to go.
