Problem with ViewParameter using Ajax calls
if I use an Ajax Event in my case a primefaces ComanndButton then
ViewParameter are decoded, validated but not encoded.
That's a problem when requried is set to true in ViewParameter because
validation set submitted value to null and encodeAll should set
submitted value to current value. But encodeAll is never called during
an Ajax request and so the next state saving writes submitted value with
Now submitted value is also restored with null value an required
Is there a way to encode ViewParameter in an Ajax Request?
