Map Canvas question

[strawman]

Folks,


I have a Canvas class for the purpose of displaying CloudMade Map (called thru JSNI) which needs a DIV ID sent to it.

I extended Canvas, and overrided getInnerHTML() to plant my div id.

All is well to display this map.

However, when I tab away from it (the Canvas is in a tab pane), the map is never hidden. How do I make this Canvas to be managed by SGWT?

public class MapCanvas extends Canvas {


    public MapCanvas() {

        setRedrawOnResize(false);
        setAttribute("_redrawWithParent", false, false);
        setAttribute("_clearWithRemoveChild", true, false);
        setOverflow(Overflow.VISIBLE);
    }

    public String getInnerHTML() {

        return "<div id=\"mapCanvas_widget\" style=\"width: 800px; height: 600px\"></div>";
    }

}

I am using the latest build (Dec 14) from SGWT.

The same does not happen when using Google's MapWidget. That works fine.

I am sure I am missing some functionality at the Canvas level.

Thanks
