Subject Re: checkmodified=”true” on a chain resolver’s child resolver
Date Tue, 14 Sep 2010 16:56:44 GMT
I’m very pleased to say… My bad.

I’ve managed to get checkmodified behaving exactly as I would expect it to
behave on a child resolver within a chain. Looks like there was some
weirdness about a test I was running.
