[Zope3-dev] Adapt to IContainer

[os]

Hello!
I not have problem with adapt my object to IContainer. 
But i have problem with usage standard zmi for her.  
Details:
1) i have SimpleObject 
2) now i want adapt my SimpleObject to IContainer 
	2.1) i create SimpleFolderAdapter->icontainer unit-test -> Ok
	2.2) configure -> ok
3) i want use standard zmi for manage my SimpleObject as container ->
problems:
	zope.app.container.browser: adding.py - 71,73; contents.py -120
        zope.app.container: constraints.py - 186
 ...

I solve problems rewrite this rows. For example:
container[name] = content  ---> IContainer(container)[name] = content 

Question: is it bugs?
Thanks!
