Structure Type expects Setter during Unmarshalling?

[kjordan2001]

I have a collection of objects similar to the Collection object in the Books example on the website, however it crashes when it gets to unmarshalling it since it seems to think a setter is required for structure types. I believe the code fix should be:
$setter = $ast->getSetMethod();
if ($setter != null) {
$parentObject->$setter( $parsedObject );
} else {
return $parsedObject; //No setter, so something else must be doing something with it, like putting it in a collection.
}

And actually that may need to be $newObject since sometimes $parsedObject is null but $newObject is still fully populated.
