> Sample code:
> {code}
> ...
> <composite:attribute name="beanAndValue" />
> ...
> <rich:pickList value="#{cc.attrs.beanAndValue}" ...
> {code}
> I tried adding a type java.util.Collection, or java.util.List, but this had no effect.
> Note that it works when the picklist is outside of the composite component.
> It also works with an h:selectOneMenu works with similar code:
> I have NO trouble passing a list to the value of h:selectOneMenu !
> {code}
> ...
> <composite:attribute name="beanAndValue" />
> ...
> <h:selectOneMenu value="#{cc.attrs.beanAndValue}" ...
> {code}
> As this works outside the composite component and with similar components (selectOneMenu), I assume that the rich:pickList is not easy to integrate with composite components for some type issue, maybe the type gets lost and the picklist is very strict about it ?
