What I really need to know is if Struts can populate a Collection class instead of a String[] for arrays of fields. It acts like it can't but I may be missing something.
I think the problem is that the EL requires my custom Collection and struts requires a String[].
Thanks,
David

If I'm seeing your problem correctly, you probably know by now that the
EL only references bean properties, except when it's referencing
collections :) . It checks whether something is a collection before it
checks whether it is a bean, so creating a SUBCLASS of a collection
class and adding bean properties won't work. You'll have to have a bean
class that has a collection property, AND a size property. Try
restructuring your bean to deal with that and see how far you get.
