cellBrowser placed in composite - do I have to attach directly to the rootpanel (or rootlayoutpanel)

when using a cellbrowser and adding that widget to a flowpanel (to be placed wherever, downstream), for some reason the end result is dead (a blank screen)...vs if I add directly to the rootpanel (or layout panel)

Also had the same problem. I had to use a <g:HTMLPanel> as the parent of the CellBrowser (as seen in the GWT Showcase).

below is the code for the composite...essentially, what I'd like to do is in another class, attached this composite to a flowpanel and do whatever with it...but, the reality is, I have to attach is directly to the RootPanel (or RootLayoutPanel)...any other abstraction causes it to bail

for example 

FlowPanel fp = new FlowPanel();
V2_M76Rolodex v = new V2_M76Rolodex();

fp.add(v); // not going to work

RootPanel.get.add(v) works


public class V2_M76Rolodex extends Composite {

/*
a bunch of code here for getting data and 
populating the tree - works, not at issue or relevant
*/

 public V2_M76Rolodex() {
       TreeViewModel model = new CustomTreeModel();
       CellBrowser browser = new CellBrowser(model, null);
       browser.setKeyboardSelectionPolicy(KeyboardSelectionPolicy.ENABLED);
       browser.addStyleName("rolodex_cell_browser");
       initWidget(browser);
 }

}

Do you have some sample code that will reproduce this?
