Problem using listShuttle

[lmk]

Hi all,

My question concerns the listShuttle, probabaly I have a problem with the converter used by listShuttle. I have two listShuttles displayed according to a4j:suport request inside a selet radio button.
I often get null value expression or invalide value expression.
inside the converter I only define the methode getAsString because I dont want to do hibernate query inside JSF converter.
is the converter mandatory for the using of listShuttle? and when it is used by this component..

how to avoid this kind of error.

thanks

Yes converter is mandatory for listShuttle and orderingList components.

we cannot return null object on getAsObject function?

I define the converter and still get error;

"Component form_id:j_id192 has invalid value expression com.user.package.User@d6fc23"

need to override equals and hashcode methods,
I think its not judicious to use dao objects directly on listShuttel, I'll use a value object.
Why JSF is so constraining !!!
