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;
}

I've taken my tree component and added some CSS to enable a scroll bar
around it when it becomes large enough:
inlineStyle="width: 200px; height: 400px; max-height: 400px;
overflow: auto; ….
This works well, but as I expand and collapse nodes in the tree, the scroll
position isn't maintained due to the component being thrown out and
reconstructed via PPR. I wish there was an onscroll on the tree, as this
would give me the hook I need to save the position and I could restore it
via window.onload, but to no avail.
Does anyone have an idea how this might be done?
Thanks in advance,
