[jsr-314-open] Fwd: [426-BeanValidation] Default Enablement Change

From: Emmanuel Bernard <emmanuel.bernard(a)jboss.com&gt; Date: 6 March 2009 21:03:51 GMT To: Ed Burns <Ed.Burns(a)Sun.COM&gt; Cc: Pete Muir <pmuir(a)redhat.com&gt;, Dan Allen <dan.j.allen(a)gmail.com&gt; Subject: Re: [426-BeanValidation] Default Enablement Change Hi Ed, What are you reasons for not allowing this "auto" mode by default (both for the default validator and the validate empty fields? We initially had something like you proposed but we decided to align with JPA to get a better cleaner alignment of the Java programmatic model at large (SE and EE). I can understand your uneasiness (I was a bit initially too) but I think it's for the greater of JSF and the platform, esp wrt ease of use. We are at an interesting tipping point. BV is not in applications yet so we can define the best defaults for the present and the future. It will be too late to move forward after that. Remember, if BV is not in the classpath, nothing changes. If someone wants to force the old legacy approach, it's two properties away.
