Hello René,
It works as expected. inputHidden, unlike the output, gets a local value
from the 3 that's being submitted with the form. Since local value when
validation fails, the old value can be rendered back. This is, alas, a weak
point of JSF here. Even if you set the inputHidden as immediate, it still
won't push the value back to the model until update value phase. To go
around that nuisance, we created a truly immediate inputHidden in some of
our projects that does everything during apply request values and does
nothing during the process validations and update model phase. The same
strategy would fix your issue. The most common terminology we used was along
the lines of:
<inputHidden flash="true"/>
<flashInputHidden/>
<contextValue/>
Regards,
~ Simon
