Now the funny thing is that this seems to work. I got all sorts of
exceptions at first, but they don't seem to be related to conversion.
Thanks for all your help, and I'm sorry for wasting your time on this
one. I'll get back when I find the real problem, should it be related
to struts.

Doesn't this imply that the myObjects property represents both the set

2. Is there a way to define a type converter application wide, like
"always use this type converter for setting types which are subclasses
of X" and "for setting types which are Collection"?

Hello Martin,
this would be ok, but that method doesn't exist in StrutsTypeConverter
as of struts 2.0.11, and most likely the framework won't call it when I
implement it. Or am I missing something?

Hi Jeromy
I'm not clear what the performance problem you mention could be. This
is what I'm doing myself and while my app's performance is OK, I would
love to improve it. What do you mean by (e.g. select n+1 due to
iteration)?
All the best
