It would be nice if it was possible to create simple startup and shutdown scripts using regular transformers. This could e.g. be implemented using functionality similar to custom transformers:
The tabs "Startup" and "Shutdown" would always be visible when you create a new workspace and would have fixed input/output ports. This could supplement the existing scripting possiblities (Python, TCL) and would make it easier for beginners and those with little or no programming experience.
Great idea. Seems this would be equivalent to that the user could define three workspaces (Canvases) in a single fmw file and a single FME process could run them in the order of Startup -> Main -> Shutdown. If it was possible, two or more Main canvases could also be contained in the executing sequence?
