This would work (although you'd probably want to do some sort of
in-request caching so you don't call populateList() more than once),
but I tend to shy away from making getter and setter methods for
properties have side effects like this. It's much clearer (well, to
me anyway :-) when pulling data from the model is explictly called out
in its own methods.
