I think there are two things to consider here:

1) can I create the object at all?
2) can I add it to a particular container?

so yuppies' reference to checkFactory and checkObject are definitely  
the places to start. Your use case refers not to object creation but  
containment depths so you're not checking the factory as whether you  
can create the object but the container as to whether it may contain  
the object. Surely extending the sample class to count your  
containment depth will solve the problem: raise the error and rollback  
the transaction?


PS. written without reference to the scary code but not convinced that  
extending TypeTool in anyway is a solution to anything.
