Subject Re: Quartz and enrich seem not to work together...
Date Tue, 23 Jul 2013 09:12:34 GMT
You can set idempotent=false on the file to allow it to re-read the
file always. As when you use noop=true that would otherwise imply
idempotent=true. But by setting it explicit to false will always make
the file readable again.
