>because I don't need in this :). Also, custom collections are suited better to application purposes, e.g. I can predefine element number for each particular form, also it may include not only forms but also other objects references.

I don't use it either :) I also do the custom collection of forms in the topformset, all launched with DO FORM etc NAME thisformset.childform, etc. Keeps them independent but available in heirarchical reference...
