[richfaces-issues] [JBoss JIRA] Closed: (RF-4520) OrderingList causes a "invalid value expression"

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)
