----------------------------------
Assignee: Alexander Dubovsky (was: Tsikhon Kuprevich)
> 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: Fabian Glanzmann
> Assignee: Alexander Dubovsky
> Original Estimate: 2 hours
> Remaining Estimate: 2 hours
>
> 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)
