    I concur with paragraph two - it seems that web frameworks have a way to go (excepting GWT et al) before just having getters and setters for controls, so you can drag and drop the visual part of an application together at design time, and then separately be concerned about programming the events. See www.strandz.org for an ideal way of creating a user-interfaced application, that kind of abstracts out MVC thinking...

 Well personally I think the whole POJO thing has been completely over
 done. Sure EJB entity beans were not much fun, but saying everything
 should now extend java.util.Object is stupid.  With persistence API
 entities need a bunch of support, you can use Cayenne model where you
 subclass intelligent objects, or you can use "black magic" runtime
 byte code enhancement.  I prefer the former because I can drill
 through the code, and use a debugger. However all the fashion now days
 it to go down the byte code enhancement path.

 This is particularly stupid with Web frameworks, which have recently
 adopted this fashion.  Now you see POJO's being used as a kind of a
 page, with a bunch of annotations, maybe some XML configuration files,
 and then some special byte code enhancement.  No decent windowing UI
 framework has ever taken this approach Dephi, Swing, Flex.

 The thing that I find really ironic, is that the Hibernate guys who
 were using reflection previously bet the crap out of JDO camp, because
 JDO were using invasive post compilation byte code enhancement.  Now
 Hibernate now are using runtime byte code enhancement, but have still
 manage to kill JDO, and create a new JPA based on their design.
