Hi Juergen!

Imo upgrading to JSF2 and EL-2.2. is always a good idea. I remember how nasty it was to handle
actions in dataTables in JSF1. With EL-2.2 you now can just have your action as #{backingBean.delete(currentItem)}
for example.
Or the <f:viewParam> or  <f:event type="PreRenderViewEvent" listener="#{backingBean.initMyBean}"/>

And these are just two of a long list of features which ease the life of a JSF developer in
EE6!

LieGrue,
strub
