How do you model the requirement for compensation action to be taken as a result of a normal task outcome?
Bruce Silver provided an example of the use of compensation activity here where the need for undoing the effect of an activity is triggered by a subsequent task. I attempted to enter into Intalio 5.2Beta
as
There is an error flagged on the compensation end stating that this can only be used an exception flow. This does not appear to be a restriction in the BPMN specification. How should I model this case to get an executable solution?

I worked on this a bit more (story here)
I ended up with a working compensation scenario but the process failed. Trapping the fault according to Fig 7 of the paper Working with Failure and Exceptions turned off the compensation.
Attached is a self contained project which demonstrates this final state .
Note the readme.txt file included.

The problems seem to be:
1. Adding a fault handler to the subprocess around all the compensation and normal flows turns off compensation.
2. Compensation End Events throw to a compensation activity but are not caught
