Adam Winer commented on TRINIDAD-129:
-------------------------------------

Have checked in an addDomReplaceListener() method that is called after dom replacement happens, and passes the old and new DOM objects.  Asking user list for feedback before closing this issue.

> Once we get 1.0.2 out (hopefully soon) let's look at providing
> some hooks for DOM replacement during AJAX, something
> where you get called with something like:
>  // Tellls you that oldDom is about to be replaced with newDom,
>  // and lets you manipulate the dom, or return "true" to block
>  // it or handle it all yourself
>  function domReplaceNotify(oldDom, newDom)
>  {
>    ... see if oldDom contains the tree...
>    ... if it does, copy scrollTop and scrollLeft into newDom
>    // And let the system handle the move for you
>    return false;
>  }
