UISelectMany collectionType ignored when VE resolves to non-Collection

[BalusC]

This,

private Map<String, List<Entity>> entitiesByKey;

<h:selectManyCheckbox value="#{bean.entitiesByKey[key]}" collectionType="java.util.ArrayList">

isn't working because VE resolves to java.lang.Object instead of to an instance of java.util.Collection.

When VE resolves to java.lang.Object while collectionType is explicitly mentioned, it should be used to create the Collection instance rather than defaulting to an Object[]. Currently, the collectionType is unexpectedly ignored when VE resolves to java.lang.Object.
