I'm writing an GUI app that uses multiple nested notebooks each with several sizers (~100) and each has a unique name.
When I attempt to use the frame designer the following exception is raised:
Exception: Collection body _init_coll_<mySizerName>_Items not in init, body, fin form
It's possible for me to alter the name of this function and make the exception go away for this particular sizer, only to have the same exception referencing a different sizer.
I admit to adding (copy/paste) many of these sizers and related functions by hand rather than using the frame designer, but they are all added correctly (ie: the sizers work and the GUI looks right).
Is there some sort of meta-file that I'd need to alter to make the frame designer function again.
