Subject [Struts Wiki] Update of "StrutsCatalogLazyList" by NiallPemberton

  === Still not very satisified ===
  I'm still not happy with the solutions provided (including my own). Many of the above solutions
assume you know how deep your items are nested, or that you create nested objects up front
that can handle the lazy situation. Where I'm not happy is where you can get back a nested
structure of unknown depth. I have a case now where the generated content that can be editable
is a questionnaire and each question can end up having sub-questions. Other than using Session
scope I'm not sure of the best approach to use. I'm messing around with LazyDynaMaps to see
if that might work. Not the ideal solution since I'd prefer to use straight value objects
from the midtier, but I'll compromise if need be.
+     ''[ NestedLazyBean] does n level
indexed properties. For straight forward object graphs (e.g. {{{person.address.line1}}}) where
you want an "address" !DynaBean automatically created when {{{person.get("address").set("line1",
...)}}} is called then its slightly more problematic, since how do you know when it hits {{{get("address")}}}
that it should be a !DynaBean property rather than some other regular kind? Using !BeanUtils's
'''Map''' notation (i.e. using {{{person[address][line1]}}}) works from a !LazyDynaMap PoV,
but you will need the [ BeanUtils
1.8.0-BETA], since nested maps were not supported until that version.''
