An automatic trigger in workflow appears possible from FTP'd content but to soon to be involved in zope heirarchy. You can get hold of the state_change object from the workflow itself but methods that would normally be available such as its data attribute or manage_ xxxObjects type methods are unavailable since the object does not enter the heirarchy until the FTP transaction has completed. A FTP 426 Error results with any attempt to use any of these methods.

But it is still possible to use the automatic transition and obtain the body from the FTP request and do something with the file data. The automatic transition I am writing involves removing the object after it has been transferred to the site (since it is only used to make a few objects, the data is large and not important to store it afterwards). So am able to use the data from the object being FTP'd in the automatic transition's script (which is good) but am looking for a solution to provide the FTP client with an 226 Transfer complete message to complete its transaction after doing what I want with the data (without the file landing in the folder).

manage_delObjects cannot be used in the script since the object is really not in the folder itself until after FTP transaction completes. The problem with letting the FTP transaction complete is that I cannot think of a way to have a fully automatic process - since automation in workflow with any number of states would still be sequential and before FTP transaction is complete. So I would likely have to cron a process to clean up the folder (which is undesirable).
