That may have more of a symptom than the cause. The other widget I
defined was:
def choice_widget(field,value,labels,required):
"""
Widget to substitute a pup-up menu with a set of radio buttons
"""
id=field._tablename+'_'+field.name
sro = []
i = 0
selected = False
for x in labels:
if str(value)==str(i):
sro.append( OPTION(x,_value=i,_selected="selected") )
selected = True
else:
sro.append( OPTION(x,_value=i) )
i += 1
set = [x for x in range(len(labels))]
if not selected:
sro = [OPTION('', _value=-1)]+sro
if not required:
set = [-1]+set
kw = {'_class':'integer', '_id':id, '_name':field.name,
'requires':IS_IN_SET(set, error_message='required
information!')}
return SELECT(*sro, **kw)
And here's an example of its use:
db.define_table('tbl', SQLField('field', 'integer', widget=lambda
a,b:choice_widget(a,b,['a','b'],True)))
When I bring up an insertion form (through appadmin or my own
controller), all is well. But if I try to submit, and there is an
error (as there will be if nothing is changed), the nesting originally
described appears on the page w/ the error message (for a SELECT,
you'd have to view the source to see the nesting). If I reload the
form, the nesting appears (but the error messages do not). If I
navigate away from and back to the insertion form, there's no nesting
(and no error message).
Thanks again,
Scott
