Why does Mule FTP connector doesn't delete file when streaming is enabled

Question

This is the relevant part of my mule-config

Answer 1

As you've seen in https://stackoverflow.com/a/17974787/387927, the answer to Q1 is: because a transfer is still running, as the transport is in streaming mode, Mule will not issue a delete.

The answer Q2 would be to get a hold of the FtpConnector via the registry, get an FTPClient instance with getFtp(uri) using the URI of your FTP endpoint then call deleteFile on the FTPClient.
