Important update for IBM Rational Requirements Composer version 4.0

Users might encounter a problem where they no longer have access to view/update artifacts in Requirements Composer until the system is restarted. The problem can manifest in a number of different ways, as described in the Symptoms and Work Items below. The defects have been resolved in the 4.0.0.1 release, and a patch is available for the 4.0 release which can be obtained by contacting IBM Rational Support.

NOTE: If the problem is not resolved after restarting the server please contact Support for information on how to identify and repair the type system.
