Reparing would not cause a problem as long as you always use the "parent" keyword to refer to the parent object.

I'm far from a QtQuick expert but I suspect the problem is that the Flickable's contentHeight, which you defined as the height of the children, is less than the full page height. Thus the bottom anchor is not at the page bottom, but at the bottom of the "content".

(If you don't want to be "flickable", why don't you put it outside the flickable?)
