Subject Re: Tree default expanded ??
Date Tue, 07 Oct 2008 11:21:20 GMT
Hi Jan,

            Thanks for your reply, i am using struts 2.1.2, and for testing
i added a simple code like this...

dojo.event.topic.subscribe("tree/treeCreate", function treeCreated(node) {
        alert("Tree Loaded");
});

this is not fired after page is loaded. if possible can you give your tree
and div construct also here?
