How Can I See Which Attributes are Changing in a Server-Side Pre-Condition?
In our process, we disallow changes to work items once they have entered a "closed" state. In addition, only certain power users are allowed to re-open closed work items. One of our users has requested that we provide a means for them to add comments to closed work items, but continue to restrict all other changes.
We think the best way to support this would be to create a server-side pre-condition operation behavior that checks on work item save to see if the only change is an added comment. I'm unsure how to do this. I think I know how to check whether a specific attribute has changed by comparing the old state and the new state, but I have two issues with that approach:
Is there a way to see what exactly changed in a work item without explicitly checking a specific attribute? Ideally, I'd like to get an enumerated list of changes. |

1. works for pre-conditions
2. far as I know, there is no list of just changes but you could make a list pretty easily.. from the oldState get the list of attributes WorkItemServer.findAttributes(projectArea, monitor) - have to load access to the IWorkItemServer service then loop thru the old-state workitem (hasAttribute == true) compare attribute old = new if not equal, add to a list collection if handles compare UUIDs for equal once done, then process the list Nate Decker selected this answer as the correct answer
Comments Thanks. That is helpful. I'll try to head down that route and if I'm successful, I'll come back and mark this answer as accepted. and u can see how to handle different attributes here in my utility that dumps the attributes of workitems found in a query result list (accepted answer)
