Missing getter for activityID on Execution-Interface?

Hello folks,we use our own custom-built visualization component to render BPMN 2.0 process diagrams and to visualize process state during process execution. To achieve the latter I query for all active tasks belonging to the process instance in question and retrieve their IDs. This is done using a T

That's a pretty complex use case you have there … which is why you have to do the cast probably.

In my opinion, it is better to build your visualisation tool on top of the executions, since you will be able to cover more types that way.
If you feel that casting is an ugly way, why not simply use a custom NativeQuery? Then you can also just fetch exactly what you want.

Hi Joram,

thanks for your response. I changed my code to base upon the executions which works fine for me now. However I still don't like the cast I have to use. I still see no reason why one should prevent access to the activityID in the Execution-interface. Most (if not all) other interfaces also expose their activityIDs to the API. Since I was not able to find a matching issue in JIRA I created a new JIRA issue for this:

http://jira.codehaus.org/browse/ACT-1616

P.S.: Accidently I hit "Save" without having finished typing my issue description. Please see my comment on the issue and add my description in the comments as the description of the issue. Thanks.

Best regards

Sebastian

No problem. And myself, I don't see any issues with exposing it actually.

thanks for creating the issue!
