RE: [cinjug-users] Struts 1.0.2 problem JDK1.3 vs JDK1.4

[Creighton Kirkendall <ckirkendall@xxxxxxxxxxxxxx>]

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" %>' />
