That should work. Note, INPUT inherits from DIV, and all named arguments to a DIV get added to the .attributes attribute ( http://code.google.com/p/web2py/source/browse/gluon/html.py#630). DIV also overrides the __getitem__ method ( http://code.google.com/p/web2py/source/browse/gluon/html.py#687), so input['hideerror'] will retrieve the hideerror attribute from input.attributes (i.e., it is equivalent to input.attributes['hideerror']). Finally, the hideerror attribute is retrieved during serialization in the INPUT.xml() method: http://code.google.com/p/web2py/source/browse/gluon/html.py#1661. > The hideerror flag seems to work if you do this, though: > > input = INPUT( _type='radio', _name='age', _value='5', _id='age5', value= > self.request.vars['age']) > input['hideerror'] = True > > I see nothing that transfers the hideerror argument from the constructor > to a property of the input object, where it needs to be during > serialization.
