Maybe the simplest solution is to use session for storing this data,
in update you check if there is 'myarg' in request, and if so then
put this into session. If there is no 'myarg' in request
you get this from session.
If you want this passed via POST/GET then you may try with
hidden() method of widgets, or write own widget that
renders as a hidden input, like:
def _toFieldValue(self, input):
and assign this widget to field that will represent 'myarg':
You will possibly have to change the line:
data = self.request['myarg']
because your input will have form prefix.
I'm not sure, but you may have some issues with this solution
when doing resetForm etc.
