deleteCasade() does not delete children of children and does not really cascade beyond one level down #112

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. create a parent-child-subchild relationship
2. delete(true) or deleteCascade() the parent
3. children are deleted, subchildren are not

What is the expected output? What do you see instead?

I would expect a deleteCascade would cascade deletion by traversing the entire 
association graph. It might be nice to provide an option to allow deletion of 
entities in this way when needed.

Perhaps we could specify with annotations? Something like @OnDelete(cascade = 
Cascade.ALL) or @OnDelete(cascade = Cascade.CHILDREN) etc. Just a thought :)

annotations are defined during declaration, but we need to make a choice in 
client code. Having two independent methods makes more sense
