Subject Re: Using Cayenne Servlet Filter can bring the web application down
Date Mon, 14 Sep 2009 14:03:00 GMT
Hi Borut,

I'm just curious if you are still using Tapestry 5 (and if using
Cayenne with T5)?  I also liked your blog where you were writing about
T5.  I found that useful when I was just starting to read about T5 and
get started in it (I'm still learning, of course -- no expert here).
