-------------------------------

        Description: 
I have trouble passing a list to a rich picklist value which is located inside a composite component, my value is an ArrayList.
My bean is in viewscope.

The problem occurs while submitting the form:

{code}
javax.faces.FacesException: ModelType (class java.lang.Object) must be either an Array, or a Collection

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 ?
