Ok, here I encountered another related problem.
I use an ajax form to dynamically lookup some data.
Namely - that is city name and longtitude/latitude.
jquery shows to the user if something he typed in has a lat/lon pair
in the db or it has not.
if db doesn't contain that pair - user have to specify it on the map
(thanks openstreetmap.org).
On submit jquery puts the lat/lon from the map to the hidden fields
(which I add to the form in the controller).
BUT. If form,accepts() returns false because of any reason -
I do receive lat/lon values in form.vars but on subsequent form
display hidden fields are empty.
IOW - INPUT._traverse for the hidden field doesn't set the '_value'.
It only sets the 'value' but you consider it to be invalid element for
a hidden field.
For now I solved my problem this way:
+++gluon/html.py @line 701 def _validate(self):
self['value'] = value
+ if self['_type'] == 'hidden': self['_value'] = value
requires = self['requires']
So is it still just inconsistency in manual?
