New GoogleMaps Example - will convert KML to GPX

Dear httpunit developers,

Revision 952 has a new GoogleMaps example which even has 
some usability for owners of Garmin GPS devices:

http://httpunit.svn.sourceforge.net/viewvc/httpunit?view=rev&revision=952

The example will take three command line parameters 
representing the start and destination point and the 
filename where to store the result.

The task is then to visit the Google Maps web site ask 
for a route between the start and destination point - 
get the result as a KML file and convert it to Garmin 
GPX format. 

Before this example it took me quite a bunch of tools to 
get the same result. With httpunit it's less than 200 
lines of code and my MapSource 6.13.7 will happily read 
the resulting file and display the route (even if it's 
from the other side of the world ...)

Enjoy!

One quirk I had to work around was the it's not possible 
to set hidden input field/parameter values with the 
current state of 1.7. 
So
	// request.setParameter("output", "kml");


in the example didn't work because it throws a 
MissingParameterValueException so I commented it out.

I allowed for the following work around now:
    FormParameter parameter = lookupForm.getParameter( "output" );
    FormControl outputControl=parameter.getControl();
    outputControl.setAttribute("value", "kml");


The necessary changes in visibility are an unwanted side 
effect. I'd rather like to add a function for this like 
"overrideHiddenParameterValue" ...

Any thoughts?

Yours
  Wolfgang
