Detailed Description

Sets a keypath to a value. This is useful when you want a part of the page rendered with different settings. The value is re-set to the old value outside of the component.
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 the the typical scenario where you iterate over keys of 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

source the source object sourceKeypath (optional) the key path off the source object. If omitted, the source itself is used. destination the destination of the value destinationKeypath (optional) the key path off the destination object. If omitted, the source itself is used.
