I have one more quick question I have downloaded workflow2 module and I have 2 different projects "Offline" and "Approval". When I move the file from one project to another can I catch this event? for example I have test.html file in "Offline" project when I move this file to project "Approval" I want to catch this eveny. Can you tell mehow can I do this?
