Hi...
I think I already posted that code snippet to the list, but here again just
for you! ;)
The code expands all nodes in my tree, and preselects a node.
After all is done, it publishes a topic to notify a sx:div to refresh...
Possibly not the best solution, but working fine for me!
dojo.event.topic.subscribe("tree/treeCreate", function treeCreated(node) {
var nodes = dojo.widget.getWidgetsByType("StrutsTreeNode");
var i;
for(i=0; i< nodes.length; i++) {
nodes[i].expand();
}
var node = dojo.widget.getWidgetById("<%=
request.getSession().getAttribute("PreselectedCategory") %>");
node.expand();
node.markSelected();
document.DocumentListSelection.NodeID.value = <%=
request.getSession().getAttribute("PreselectedCategory") %>;
dojo.event.topic.publish('ListSelectionFilled');
});
Regards
Jan
