[Boa Constr] _init_coll_..._Items sizer problem

[mindy e. <min...@gm...>]

Hi,
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:
Boa Error
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.

Thanks

No there is no meta-file, Boa uses the source code directly.

I am pretty sure that when you did the copy/paste you misnamed something 
and Boa can not find it anymore, it might still be valid Python code and 
might still work but if the code does not comply with the Boa naming 
standard then it will not work (this is only true for the generated 
section of the code).

Check the code again, if you can't find it attach it here and I will try 
and have a look.

Thanks for the response, Werner.
I figured out the problem: the "init, body, fin form"  is actually a  
specific format that the generated method must be in in order for  
BoaConstructor to interpret it correctly.
The format is something like:
def _init_coll_sizername_Items(self, parent):
	# generated method, do not edit

	sizername.AddWindow(blahblah)

*** the comment and/or the newline between the comment and the function  
body are important ***

Thanks again
