public class ERXKeyValueSetter
extends ERXDynamicElement

Sets a keypath to a value. This is useful when you want a part of the page rendered with different settings. The value is changed before its children will be processed and is re-set to the old value after their processing.
One way to use it would be in a D2W app, where source="edit" and destination=d2wContext.task when you are on a list page. Another would be the typical scenario where you iterate over keys of a dictionary and you want the corresponding entry. Normally you'd need an accessor for that, but using this component you would set source=myDict, sourceKeypath=currentyKey and destination=currentEntry.
