Actually I think that was a red herring - setting the parentElem style
just forced a re-render and changing the map size had the same effect.
I think the problem is due to the map trying to initialize itself
before layout() is called. If I add a holder panel like this:
SimplePanel holder = new SimplePanel();
p.add(holder);
and then add the map after layout() like:
p.layout();
MapWidget map = new MapWidget(LatLng.newInstance(50, 50), 8);
map.setWidth("100%");
map.setHeight("100%");
holder.add(map);
it works.
I have one question about threading in the browser - I have used YUI
LayoutManager which is very similar to DockLayoutPanel.
http://developer.yahoo.com/yui/examples/layout/nested_layout.html
If you want to nest layouts or use a map inside a layout you need to
register a listener for an onrender event. When I asked why, Dave
Glass said that although the JS is single threaded, the DOM elements
will not be created by serially so you must wait until the event fires
before you can safely layout nested items that depend on the parent
layout.
Could this be a problem here also?
Thanks,
John
