Ahhh really close! Those fixed the earlier problems I get output that technically looks correct.
The only issue is I seem to be getting a double ending LI like so:


After each list item. And when a UL starts, it must start in an OPEN LI like so:

<li>blah blah


I could probably live with it if it closes the top LI but still puts the nested UL in the same
place. I'll play with it some myself but if anyone has any other ideas...

Thanks a BUNCH Hassan! For review, here is the current iteration of the code:

	ListIterator verticalNodes = nodesInVerticalOrder.listIterator();
	if (!verticalNodes.hasNext()) return;
	int level = 1;
	int previousLevel = 1;

	StringBuffer dataCell = new StringBuffer();
	StringBuffer javaScript = new StringBuffer();
	// start UL

	// iterate through each nav item and write it out
	while (verticalNodes.hasNext()) {

		MenuItemNode node = (MenuItemNode) verticalNodes.next();

		previousLevel = level;
		level = node.getLevel();  // # from 1-4
		if ( verticalNodes.hasPrevious() )
		if ( level > previousLevel )
		if ( level < previousLevel )
		// begin new list item, write out class name and link
		dataCell.append("<li><a href=\"" + node.getHref() + "\"");
		//close the href, write the anchor text, close the anchor.
		dataCell.append(">" + node.getTitle() + "</a>");
		// end of list item and link

		//close the LI item
	// close out the UL
