Amy,
I don't know if I understand you problem. When one operation fault, I
guess this
operation is finished, therefore there is no way receive many faults
with the same
operation. I think you have other problem...
If even so you want do cancel this operation I will do this:
At then end of execute function, put this line:
taken.operation = _ro.getOperation('getServices');
In line with ??? replace for it:
var operation:Operation=token.operation;
I don't know if it will run, I don't test it...
