Modifying an instance with Javascript instructions is always problematic 
because of dependencies to be set for refresh. It could also be very 
specific of a version of en implementation...

Maybe the best way would be to just define an extension for submission: 
instead of "http:" or "file:", "javascript:" could be used to retrieve a 
string from a Javascript instruction.

You could then externally activate a submit action for it.

What do you think?

Thanks!
