Looks like you're using the nested properties syntax in Struts, so the
object coming out of the locations ArrayList should also be a bean. So my
question is, does the object coming from the ArrayList have a getter for
active (getActive())?

Based on the struts documentation:
http://jakarta.apache.org/struts/faqs/indexedprops.html
this is the correct way to handle indexed properties and remember it
does work fine under 1.3 . I should not have to cast the object because
remember this is handled struts tag as an interpreted language and not
as compiled java so casting is not necessary. Does any one know of
issues with struts 1.0.2 and jdk 1.4 specifically with indexed
properties.
<html:checkbox name="computersForm" property='<%= "locations["+i
+"].active" %>' />
