Displaying errors in Team Advisor with Operation Participant

Hi

I am using operation participant to do some operation (like creating the RTC project area) but I can't see any method to display the error in the Team Advisor and stop the save operation.

But in case of operation advisors we can use the method collector.createProblemInfo();

So is there any way to display the errors in the team advisor for operation particpant?

Please let me know if anyone has any idea about this.
