Isn't this recursive? pattern="foo/**.xml" and generate 
src="foo/{../1}.xml" refer to the same pipeline. Is that a good idea?

One other thing to check is the redirect. Note that this is doing an 
HTTP redirect, and therefore the way they work can cause this sort of 
thing if not used right. Read the doc page on redirects for more info. 
(Head thick with a cold - can't give more right now).
