2.0.8
> UIComponentBase.getFacets() should support all Map methods

> The javadoc of UIComponent.getFacets() says this:
> "... Return a mutable Map representing the facet UIComponents associated with
> this UIComponent, keyed by facet name (which must be a String). The returned
> implementation must support all of the standard and optional Map methods,
> plus support the following additional requirements:
> - The Map implementation must implement the java.io.Serializable interface.
> - Any attempt to add a null key or value must throw a NullPointerException.
> - Any attempt to add a key that is not a String must throw a
> ClassCastException.
> - Any attempt to add a value that is not a UIComponent must throw a
> ClassCastException.
> - Whenever a new facet UIComponent is added:
> - The parent property of the component must be set to this component
> instance.
> - If the parent property of the component was already non-null, the
> component must first be removed from its previous parent (where it may have
> been either a child or a facet).
> - Whenever an existing facet UIComponent is removed:
> - The parent property of the facet must be set to null.
> ...."
> The current implementation is not strict about "... the returned
> implementation must support all of the standard and optional Map methods
> ...". There are ways to modify facet map indirectly, using iterator.remove(),
> or entry.setValue() or removing some key, value from entrySet(), keySet() or
> values() collection.
> These methods are not very common, so in normal use cases there is no problem
> at all, but at the end this should be done to prevent bug reports like
> MYFACES-3227, MYFACES-3175 or MYFACES-2407.
