Robert,
Damn, I was just replying to your original note when you posted ;-). I'll
include my response below in case the "two-step" idea appeals to you:
Not sure if you've moved on from this, but I think you're either gonna have to
change the structure of your data or access it in multiple steps. Assuming you
can use JSTL and you want direct access (vs. looping) to the nested object at a
given index, I think you could do:
<bean:define id="sublist"
name="form"
property='<%= "list[" + index + "]" %>'/>
<c:out value="${sublist[index].productId}"/>
P.S.
I just checked and there's no Struts-EL version of <bean:define>? Would've been
helpful here. One of the implications is that "index" has to be both a scripting
and scoped variable.
