Well CourseContext has a member var named _tt_set_id, which is the id of a
ThinkingTypeSet object residing under that given CourseContext.
CourseContext.get_thinking_type_set looks for a child in self, named
_tt_set_id, so just deleting and replacing the object would not suffice.

> 1. Should I do that?

No.

You should separate the code to copy the thinking type sets to their own
methods, and put some very nasty ui in place. I.e. have manage_afterAdd call
that same functionality, and have it also available via a web interface.
If you just need to change the thinkingtype set in you active course
context, just write some code to change the CourseContext._tt_set_id, and
copy a new ThinkingTypeSet into the CourseContext object.

The next generation of Fle will without doubt be written in pure, functional
scheme, so as to avoid those pesky little side-effects. We'll have Janne
fill in here with more info on this. :)

To my knowledge there is are no 'invisible' objects in FLE. Care to
elaborate?

1.4 will cure cancer, fix the famine in third world countries, and bring
world peace.
