Hi...
just try to add this short script to the page that contains your tree...
Might possibly be not the most beautiful solution, but works for me!
dojo.event.topic.subscribe("tree/treeCreate", function
treeCreated(node) {
// get all treenodes and iterate through
var nodes = dojo.widget.getWidgetsByType("StrutsTreeNode");
var i;
for(i=0; i< nodes.length; i++) {
nodes[i].expand();
}
//Just another thing you might find useful - preselect another
node
var node = dojo.widget.getWidgetById("<%=
request.getSession().getAttribute("PreselectedCategory") %>");
node.expand();
node.markSelected();
// Thats how I use the treecontrol to refresh a list...
document.DocumentListSelection.NodeID.value = <%=
request.getSession().getAttribute("PreselectedCategory") %>;
dojo.event.topic.publish('ListSelectionFilled');
});
Hope that helps!
Regards Jan

Betreff: Re: Struts 2.1 Tree Problem
i found solution to the parent node item.
here is the code snippet ..
*tree construction *
<sx:tree id="contentTree" name="contentTree"
label="Root" treeSelectedTopic="treeSelected"
expandedNotifyTopics="treeExpand">
-----
-----
</sx:tree>
*java Script code *
<script language="javascript">
dojo.event.topic.subscribe("treeExpand", function treeNodeExpanded(message)
{
alert(message.node.widgetId);
});
</script>
while constructing the tree expandedNotifyTopics attribute can be used to
specify the function to be executed while expanding the tree, when a node is
expanded i am taking that root node and preserve in a variable... so when a
node is selected what is there in the parent variable is the parent node.
still i didn't find a way to show tree extended default... any help is
greatly appreciated.
Thanks in advance
