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)
