The easiest solution for your problem would be to write in your
default action block something like:

     self session currentRequest isXmlHttpRequest
          ifFalse: [ " default action code " ]

I am not really sure if we want this as a default. There are several
problem serializing hidden-fields, buttons and some of the "composed
form elements" like checkboxes and multi-select lists (some of these
problems have been fixed in 2.8).

Maybe you could also trigger in your drop-down just the relevant form
elements using a cascade of #triggerFormElement:. Note this also works
for multiple forms, etc.
