OrderingList causes a "invalid value expression"
------------------------------------------------

                 Key: RF-4520
                 URL: https://jira.jboss.org/jira/browse/RF-4520
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.1
         Environment: Windows XP SP2, Vista SP1, Eclipse 3.3 (Europe), Sun JDK 1.5.015, IBM JVM (WebSphere 6.1)
            Reporter: wert wert


ManagedBean contains List of Objects
- Rendering: IO
- Extend with a4j:support works on client side
- server side a "invalid value expression" is produced

Affected class: UIOrderingBaseComponent
Affected method: isSuitableValue(Object value, Object restoredObject) (Line: 76)

return ((Collection) value).contains(restoredObject);

value contains specified Objects whearas restoredObject is a java.lang.String. So the string is compared against the object instead of the opposite!
Internally the following code is proceeded: restoredObject.equals(object)

Solutions:
- convert the Collection to a Array
- work with HashMaps whereas the key is represented by the string of the object (myObject.toString)
