How to handle empty lists?
Subject: How to handle empty lists?
From: "Scott Danzig" <da...@avaya.com>

Hi,
I'm wondering.. for something displayed using logic:iterate.. I have a form
using a multibox for instance.. nifty thing.. I'm wondering..what's the best
way to handle a list being empty? As in.. if there's no elements to
display, it should not only mention there's nothing to list in a nice little
message, but in the case of something like a multibox, the related submit
button should be suppressed too, as there's nothing to select (we're
assuming the form only contains that one multibox).. I'm still fairly new to
a lot of things in struts, so please be as comprehensive as you have time
for. Thanks in advance for what help you can offer.
- Scott

Look in the javadocs for the logic:NotPresent tag...
