that needs quite a long explanation, I'll try to give you a short one ;)
there are three states your component values can be in:
- set as a submitted value (done in decoding phase)
- set as a local value (done after conversion and validation has been
processed, this is when setValid() is called, you don't have to do it
yourself)
- set in the backing bean (done in the update model phase)
so in decode, you need to set the submitted value.
for conversion and validation, you have to make sure that the value is
convertable and valid, else the local value will never be set.
if the local value is set - and all other components on the page have
valid values, the value is written through to the backing bean in the
update model phase.
somewhat clearer?

Martin
