Keith,
Where is the exception occurring? If it is happening in the
LookupDispatchAction (or DispatchAction), then you could implement a base
action class and override the execute method. In the overriden execute
method, you would
(1) Get the parameter name from the mapping (mapping.getParameter())
(2) Get the parameter from the request.
(3) If a value is returned, then return super.execute(...). Otherwise,
return unspecified(...).
The coding of the URL (foo.do?browseType) causes unspecified to always be
executed. When the button is clicked, the value associated with the button
is not assigned to your browseType parameter. I believe this is normal.

You know I was just thinking about doing "/foo.do?method" when I read your
post. I stuck it in there, but that didn't work.
Then I tried "/foo.do?method=" and "/foo.do?method=label.modelBrowse" and
"/foo.do?method=model". Now it executes the 'unspecified' method no matter
what I do, even if I click on one of the buttons...

With the stable release of 1.1 you need to pass the parameter through
usually
/foo.do?method=save
but to get the unspecified method running
/foo.do?method
suck it n see.
