Because you have "@process.new", the "on_create" validations will be
triggered.
If you are updating an existing record, use
@process = @process.find(...model-id...)
where model-id is usually taken from "params" (params[:id]).
Then assign the new values to @process.
Then the "on_create" validations will not be triggered.

Hope that helps. I think your "doajaxing" method needs to know about the
two cases, create/update.
