I am trying to get the dynamic update to work and have been

I am trying to get the dynamic update to work and have been through your
docs but am still not sure what I need to call/set. Here is what I have done:

  1. In my xml, I have added the property child=“1” for nodes
    with children child=“0” for nodes without children

  2. In the html page which houses the control,
    through Javascript in the onLoad event (page load), I call
    tree1.setXMLAutoLoading(url). My assumption is that the url specified will be
    called whenever the user attempts to expand a tree. I have a breakpoint set and
    the URL NEVER gets called. Is there something else that I need to do to make
    this happen?

You
don’t need to specify any additional commands to enable dynamical loading (but
you still need to call tree1.loadXML(url) method to load first level of the
tree).

(see
in documentation samples/treeEx31.html)

Also,
In case of old Tree code problem can be caused by IECaching issue, you can try
to execute

                tree.preventIECashing(true);
