[jsr-314-open] <h:dataTable> binding vs. ui:repeat

[lincolnbaxter at gmail.com]

I didn't want to go that route because it wouldn't have used the existing tags designed for actionlistening and etc, therby introducing another thing people would have to learn, whereas this sort of silently/naturally extends the existing tags. 

I don't see any reason why we couldn't, but ill leave that to others to discuss since I'm not as familiar with f:event

I do remember some discussion of providing component system events for 
events that are currently handled via FacesEvents (valueChange, action), 
but I guess we never reached a resolution on this.  If we were to add 
such system events, are you thinking that these should replace the 
existing FacesEvents (ValueChangeEvent, ActionEvent)?  Or would the new 
system events simply complement the corresponding FacesEvents?
