Must page subform be flowed for page's other subform content to flow across page break?

[#1]

I'm having trouble getting content to flow across page breaks.  For example, I have a positioned subform wrapped within a flowed subform.  I've tried various combinations of the "Allow page breaks within content" settings for those subforms.  However, I can only get the content within those subforms to flow across a page break if I set the page subform itself to flowed.  I'd rather not do that, because it necessitates substantial further design work on the entire page.  Is it essential that the page subform itself be set to flowed for content to flow across a page break?  If there is a resource that discuss this specific topic please point it out to me.  Thanks.

If a object should allow page breaks then all it's direkt parents also hat to allow this.

As an example: If the nested subform "subform1_2_1" should allow breaks then its parents have to be flowed and allow page breaks too.

form1

     pageset

          masterpage1

page

     subform1

          subform1_1

               subform1_1_1

          subform1_2

               subform1_2_1 (allow page breaks)
     subform2

          subform2_1

          subform2_2

Hope this helps!

Thank you.  It also appears that the answer to my original question is "yes" (i.e. the page subform does need to be flowed--and it must also allow page breaks as radzmar explains).  I did some further experiments which indicate that, in my particular situation, wrapping objects in subforms is largely unnecessary; I've removed those subforms and things are working correctly simply with the page subform set to flowed and allow page breaks.  I still need to do some design work to account for auto-repositioning of controls on a flowed page but that's fairly easy, albeit tedious.
