Hi, what good is the onAttach method? We shouldn't encourage users initializing data upfront, as they should do it lazily on first demand. Attaching is also unreliable as when first time the page is attached, components inside repeaters aren't even built yet.
So I think we should remove onAttach while we can. The benefit would be that the code would get less bloated and we'd also save quite a few traversals (look at MarkupContainer.internalAttach2(). Looks rather scary). -Matej
