Yes, you cannot nest cftransaction tags - but there is a workaround this. You just need to create your own controller regarding who is going to do cftransaction (is it me or the other function?).
It all depends on your situation, but usually CFCs that wrap internal CFC (while themselves they are exposed) should not do directly any DB operations. This implies you may even not need a controller for the function that needs to do cftransaction. A controller can be just a function input variable (easy case) or more complex logic (I seen people do recursive functions and use this scope for cftransaction control). And on final note, it would be just nice to nest cftransactions, I think it was on CF7 wish list and I bet it is now on CF8 wish list.
