Thank you Jean-Pierre/James for your answer - what you propose is certainly
one valid way of doing it, but it is still doesnot feel like a 'natural' way
: It doesn't allow the dynamic 'navigation' of bean properties that are them
selves Collections that each entry might have other Collections etc.
For instance I might have a User which has a getFollowers() or
getLikedObjects() etc and I want to display some of their stuff, following
some display logic etc :-) Perhaps this wouldn't be the most elegant way MVC
wise, but I am not a spring/jsp/mvc expert anyway.
Surelly this isn't SDN's fault, but JSP's. It would though be very helpful
(and perhaps its a twoliner) if we could annotate @Query on more (immutable
or not) Collection/iteration interfaces, say Iterator for a start....
Regards
