Thanks for your reply
I use mozilla firebug to see whether things work as I expect or not. I could
see that populate_document_select() function gets called and
data['Document']['document_type_id'] gets posted.
I can also get the expected return value (which is the most current unused
travel document number) from the response. What I don't know is how I can
set docnum field value.
What I should do might be similar like this (calling javascript code)
document.getElementById(docnum).value = $(return value from the response
object).
But I can't figure out how to do this exactly using ajax helper options.
