Re: Problems with nested SelectOneRadio, SelectManyCheckBox, ... and panelGrid ... (SOLVED)

["R. Müller" <r....@unicomp-berlin.de>]

Hi group,

i solved my issue respectively i figured out why :

1. has nothing to do with panelGrid or selection-components :-)
2. there was a validator, which marks some input as invalid, this seems
to avoid remaining action (pushing back the values of the 
selection-components to the backing-bean) [of course, it is not the 
'final' submit ...]

regards

Ronald

Re: Problems with nested SelectOneRadio, SelectManyCheckBox, ... and panelGrid ... (SOLVED)

Ok, we could have answered that.

sorry for not doing so ;)

Indeed, that's a major stumbling point for many new users to JSF -

you'll need to add an h:messages tag in your page for
validation-messages to show up

if you don't and there is a validation error, the model won't be
updated and you won't have a clue as to why this did happen ;)

regards,

Martin
