Detailed Navigation expand node

Question

Hi everyone,
I've been trying to open by default the first node in my Detailed Navigation. I have come very close using the following code which I placed in an iView:
response.write("<SCRIPT>");
response.write("var all = window.DetailedNavigationTree.getNodes();n" +
               "dynamicLoad(all[0]);");
response.write("</SCRIPT>");
This causes the node to be open when you first click in the TLN.
I can close the node by clicking either on the text or on the down arrow next to the node. Now, if I click on the arrow again, the node opens fine, BUT when I click on the text again the node does not reload.
Anyone have any ideas why or how to work around this problem?
I've been looking at detailedNavTree.js, dynamicTree.js and dynamicLoad.js .
Any help would be appreciated a lot!
Thank you,
Regards,
Ale

Everyone,
I have found the solution. The issue was that when we clicked on the text in the detailed nav, the whole page would refresh. This would cause the menu to expand but then the iView with the dynamicLoad() was called again and automatically collapsed the menu again!
So i added a boolean in the class which makes the dynamicLoad() execute only the first time the iView is loaded.
     private boolean mDone = false;
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
         if(!mDone) {
               response.write("<SCRIPT>");
               response.write("var all = window.DetailedNavigationTree.getNodes();n" +
                    "dynamicLoad(all[0]);");
               response.write("</SCRIPT>");
               mDone = true;
Hope this helps!
Ale
