Class RowKeySetAttributeChange

java.lang.Object
org.apache.myfaces.trinidad.change.ComponentChange
org.apache.myfaces.trinidad.change.AttributeComponentChange
org.apache.myfaces.trinidad.change.RowKeySetAttributeChange

All Implemented Interfaces:

Serializable

public final class RowKeySetAttributeChange

extends AttributeComponentChange

Handles RowKeySetAttribute changes, which need to be handled specially because they are mutable and programmers assume that the instances don't change. Cases that we need to worry about: 1) old value is null 2) new value is null (should clear existing RowKeySet if possible) 3) old value = new value 4) new value is a ValueExpression or ValueBinding 5) old value is a ValueExpression that needs to be evaluated in context 6) RowKeySet is internally bound to a model that needs to be evaluated in context
