My client attempted to use Java API to modify enumerations, while modify and save a com.ibm.team.process.common.IProjectArea; multiple times with different connections to RTC,  they got com.ibm.team.repository.common.StaleDataException
https://jazz.net/forum/questions/206968/unable-to-save-the-same-projectareaworkingcopy-twice-in-a-row-stale-exception

It looks like RTC has 2 instances of the data one in the DB and another one that's cached.  Is there a method to evict the cache, or synchronize these two copies? Also, is there a way to modify enumerations without encountering the StaleDataException(generated by the code below)?

boolean saveProcessArea = false;
final IProcessArea mutableProcessArea = (IProcessArea)
fCachedService.getMutableCopy(fProcessAreaState);
if (!fProcessAreaState.getStateId().equals
(((Auditable)mutableProcessArea).getWorkingCopyPredecessor())) {
         // If the underlying item was changed in other places,
         // we need to indicate the editor is stale.
         throw new StaleDataException(mutableProcessArea, fProcessAreaState);
}

Any help on answering there will be much appreciated.
