Dynamic loading of tree data while expanding node using servlets. I have a tree with multiple levels, each will have thousands of nodes. I am trying to load entire tree at a single shot. But its taking lot of time to load. So what i need is i need to load the child nodes when i am exapanding parent node. I heard we can do by using tree.setXMLAutoLoading(url); tree.loadXML("root.xml"); But i don't have static xml file. I have to get the data from the database. I have some questions regarding above 2 lines of code. 1. Is root.xml will contain all the nodes information or only the parent node information. 2. When we are calling setXMLAutoLoading(url) - will this return only the child nodes of a expanding parent node or all the nodes information. 3. How it will understood i am expanding so and so node. Thanks in advance..... Answer posted by Alex (support) on Nov 06, 2009 02:33 Hello, >> But i don't have static xml file.
