[Zope] FTP and container type products

[Petr Knapek]

Hi Zopists,
I have created new container product 'ISNG Folder' by modification of
classical Folder object. Only some attributes are added to every instance
of ISNG Folder and in future a more functionality. 
But when I try to put any object over ftp, an error occurs. I can't
create any object inside the ISNG Folder object over ftp. I have no such
problem when putting the object into ISNG Folder over web interface. Can
anybody tell me more about ftp access and help me with my problem?

Below the part of my source is listed.

Thanks, Petr
