As of Craft 2.2 build 2579 / 2581 I get an error upon save for entires in a section that uses postDate in the URL and in the {slug}
CException Craft\MatrixBlockModel and its behaviors do not have a method or closure named "postDate".
Removing postDate from slug didn't eliminate error. Also noticed that system wanted to change postDate in slug when editing older entries.
**Any possible work arounds for this? **
