Ali,
It sounds like your almost there.
Try adding type="yourpackage.Unit" to the iterate tag
assuming that Unit is the name of your unit class.
Also if want to set the properties of nested beans
using the iterate tag I have found that it appears to
work but then does nothing. What actually happens is
that the properties are returned to the form and not
to the bean! From what I can gather from other posts
on this list it is a known issue (confirmation
anyone?) I don't know if it will be fixed in
struts1.1.
Anyway I have a work around that involves that works
for me. I'll email it to you if you want.
Sleep sounds like a good idea about now :-)
