Hi Amleto,
am using tomcat 5.5.7, jstl 1.1.2
my web.xml declaration is as follow.
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/tld/c.tld</taglib-location>
</taglib>
More over fact it's Interger not int shouldn't matter, as i said,
another webapp
which has
${param.mode=='list'} in it's test is working, that i can suppose == is
converted in EL expression
by a equals() call.
