When I remove a draft my address bar changes to the following : http://extranet.atlassian.com/users/viewmydrafts.action?discardDraftId=701694405

If that page is reloaded (for instance, returning to an earlier session in Firefox), I receive the following error:

java.lang.IllegalArgumentException: Content entity object should not be null
at org.springframework.util.Assert.notNull(Assert.java:112)

Along with a long stack trace.

It should behave better than this, and simply take me back to the Drafts page.
