This module extends Workflow by allowing CCK node fields to be made invisible or read-only depending on the current workflow state. The workflow state form is extended to show all node fields with appropriate controls to hide and/or disable each field for that particular state.
This functionality is useful when a workflow moves among users who have different permissions regarding the document flowing through them. Which is the case in most every workflow we've encountered.
WHAT'S NEW ?
The 1.0-beta1 release for Drupal 7 now makes Workflow Fields compatible with the latest stable release of Workflow (currently 1.2).
Various bug fixes and improvements were done in terms of usability and user-friendliness.
USAGE
When the module is enabled, the "Edit workflow state" page is augmented with a list of fields that correspond to the content types using the workflow. You can specify whether each field should be visible or read-only, per user role, when the node's workflow is in that particular state. The visibility flag applies to both the view and edit pages of the node.
