Creating a content view user action/action chain does not propagate SEAM session needed for FETCH->UI Selected Documents

A content view button/user action, linked to an extended MailFolder, causes GetSelectedDocuments to be called via FETCH->UI Selected Documents in the user action's action chain. Because GetSelectedDocumentsis not a SEAM component it needs to call a SEAM utility CONTEXTS via OperationsHelper to get a DocumentsListsManager instance. Since OperationsHelper is not a SEAM component the call to Contexts utility to get DocumentsListsManager creates a different SEAM session than the one needed by the content view action chain, hence, a null value returned by the FETCH->UI Selected Documents call to the action chain. The selected document cannot be read and a null value error is thrown.
