Error when saving child workItems from a Participant plugin


Emilio Iglesias Martinez (1666) | asked Feb 01 '12, 11:30 a.m.
Hi,

we are trying to develop a Follow up action with the following logic:

- When the status of a parent WorkItem changes to a "final" state (like "Done" or "Invalid"), fetch all children from the repository and set their status to the same as the parent.

We developed a participant (see code below), but we are getting this exception when the "saveWorkItem2" method is invoked:
012-02-01 17:01:04,608 ERROR com.ibm.team.process.common - assertion failed:

can someone please give us a hint of what we are doing wrong?

You have to get the workingCopy of the child workitem.. .. otherwise it is read only and cannot be saved.
