(cc'ing clojurescr...@googlegroups.com) Hi James,
Let me make sure I understand what you're asking: you have a parent enclosing component that has to do calculations to position a set of child component element, but you can only properly calculate positioning for those child elements (in the parent?) after you get offset position information for each one, once they have mounted?
