DeliverDilemmaHandler - getting access to the errors reported by RTC client

Hello to the forum members,

I am developing automation which delivers change-sets. I am using com.ibm.team.filesystem.client.operations.IDeliverOperation. This class requires an instance of com.ibm.team.filesystem.client.operations.DeliverDilemmaHandler. Up until now I used DeliverDilemmaHandler.getDefaultNoCheckIns() to get an instance of this class. I would like to display to my users the error messages displayed in RTC during failed deliver operation, such as the error message displayed when change-set contains a file locked by other.

Is there a derived class of DeliverDilemmaHandler which allows access to these error messages ?

In case the answer to this question is "no" - is there a documentation to the scenarios which activate each callback in DeliverDilemmaHandler and its base classes ? I'm asking for the documentation in order to be able to reproduce each scenario and make sure I handle it correctly.

Thanks,
Gidi
