Well, technically I could do that with the <c:if> operator as well. I just did it for
clarity of distinguishing between HTML and JSTL code. I also have other <c:choose>
situations with HTML attributes that get to be several lines long. Personally, I'm not
too worried about how the HTML source looks in the final output. I'm more worried
about
keeping my JSP/HTML original source code readable. I'm trying to be nice to those who
may
follow me on this project. ;)
Thanks for the tip, though! Didn't know the tertiary operator was available!
