The wkNotesViewProcess is another workflow control similar as simpleworklowcontrol. The difference is that it tried to define workflow process in a Notes document instead of XPage. The idea is to define the process in a Notes rich text field with xml string in Notes document. So we can separate the process definition from XPage code. It also give us flexibility to create/modify processes without changing XPages code.
But in current release, this control was not fully implemented. We may support this in future release. Thanks!
