I'm trying to setup a workflow rule that writes the values of custom fields created directly in my organization to fields that exist on a visualforce page in a managed package. The workflow rule criteria is set to "created and everytime the record is edited."

The workflow rule works as expected when on a standard page; but the workflow rule isn't triggered when I edit fields on the visualforce page.

Is there a limitation preventing workflow rules from triggering when a visualforce page is being used for both the edit and detail views of the record? If so, is there a work around? I would prefer not to use an apex trigger for this particular task.

Thank you for your help.
