After adding properties to a class

Hi all, When I add properties to a class, I need to perform "Edit Objects/Save Objects" on all documents containing an instance of that class before the new properties exist in those documents. In other words, after adding a new property "myNewProp" to class "myClass", executing $doc.display("myNewProp") in documents already containing instances of "myClass" returns nothing until I do "Edit Objects/Save Objects" on those documents. Is this the intended behaviour? It makes updating classes a little less seemless than I expected, particularly when objects of that class are very widespread throughout the wiki. Is the best solution to write a script to automate the "Save Objects" task on all relevant documents, and then execute manually it every time I add a field to a class? I'm using XWiki v0.9.840.
