Re: [Solved] JavaFlow and SuggestionLists

[Christofer Dutz <ma...@c-ware.de>]

Hi Torsten,

I am currently using an out-of-the-box Cocoon 2.1.10.
Generally there currently seems to be no way to use any of the 
IFrame-Based Cforms/Dojo widgets, because they simply can't find the 
FormInstance.

I know that this is pretty hack'ish ... but It was the only way for me 
to get everything runing without doing really big refactoring.
