Just
a short question about dhtmlXTreeObject:

 When
the xml-file it updated sometimes the menu is not updated due to a cache
somewhere. Do you know how to prevent this?

This is problem of browser/server settings, not a
problem of tree element itself.To be sure that XML is always updated from server just
add some unique info to your XML file name.

           
tree.loadXML(“my_xml.xml?uid”+(new Date()).valueOf());
