ToolStripMenuButton per rootnode

[dencel]

I have a simplistic datasource:
Menu(id,name,parent,sequence)

Now I want to create toolstripmenubuttons for each rootnode that is available. (to create a 'normal' top menu bar). I can't figure out how to do this.

I've tried the code below, to no avail:

final DataSource ds = DataSource.get("MenuDS");
ds.fetchData(new AdvancedCriteria("parent",OperatorId.IS_NULL), new DefaultCallback(){
	@Override
	protected void onResponseResult(Record[] data) {
		for(final Record record:data){
			addMember(new ToolStripMenuButton(record.getAttribute("name"),
				new Menu(){{
					setData(new ResultTree(){{
						setDataSource(getMenuDataSource());
						setRootValue(record.getAttributeAsInt("id"));
					}});
				}}
			));
		}		
	}
},new DSRequest(){{
	setSortBy(new SortSpecifier[]{new SortSpecifier("sequence", SortDirection.ASCENDING)});
}});
