Dynamic dispatch recursion shared clones error

[matt.baker]

This may be super obvious, but I'm missing it. Why doesn't this work:

I have a base class with a dynamically dispatched member VI which takes an enum and calls itself to build up a string (possibly not a great way of doing this, but disregard for the moment). A child class inherits from this and overrides the action on one of the values, but calls the parent method on the others. When I attempt to run this VI with an enum value that causes recursion (in this case "Nested 2"), I get error 0x412 / 1042. Also happens on the base class.

The member VI is set to shared clone reentrant execution on both as suggested in the IDE (pre-allocated doesn't work which I can understand).

If you create a new VI and call the method it seems to run as expected, it just doesn't seem to like running the method directly.

I wouldn't have expected this behavior but maybe that makes more sense to someone else.
