MapWidget.setUItoDefault() can short circuit MapClickHandler

[GoogleCodeExporter]

Found in Release:
r1423

Detailed description:

  In the Maps API demo, I noticed that the Map click handler in 3 of the
demos (ClickDemo, ReverseGeocode and MapEventDemo) was not always working.
 If the file was loaded from hosted mode, the click handlers did not fire.
 However, after pressing the 'reload' button, the ClickDemo started to work.  

I suspect a timing/caching issue.  

Workaround if you have one:

  For now, I am working around the problem in the demo by:

  1) Not calling MapWidget.setUItoDefault()
  2) Adding the controls separately.

Note that I have been unable to reproduce this outside the maps demo, with 
neither
straight JavaScript or a small GWT demo.

I've reproduced this issue:

- Create any map during module load and put it on the page.  
- Some time after the onModuleLoad() completes and the first map displays, 
create a
second map
- Include a click handler, 
- Use MapWidget.setUItoDefaults().  
- Display the second map on the page.

Although this is not typical for a Maps application, it just so happens that 
our Maps
demo performs all of the following.

Known workarounds.  Any single one of the measures below seems to prevent the 
bug.

- Use a single MapWidget
- If you use multiple map widgets, create them in onModuleLoad(), don't defer
creating them.
- Don't call MapWidget.setUItoDefaults() when you want to use a MapClickHandler
- Turn off the DoubleClickToZoom feature from the MapUIOptions:
    MapUIOptions opts = map.getDefaultUI();
    opts.setDoubleClick(false);
    map.setUI(opts);

A patch was applied to the GWT demo to set the UI options, turning off double 
click as 
shown in the workarounds above.
