JSP recompilation problem - losing text fragments

Question

Hi,
I'm working on Oracle JDeveloper 10G and Oracle App Server 10G (9.0.4). Have the same problem on both. The following JSP fragment:
<tr<%= (idx.intValue()%2==0)?" class=bg3":"" %> height="30">
is in a loop where idx is incremented by 1. The page compiles and runs fine initially. If it is changed, then OC4J recompiles it resulting that the even rows print properly
<tr class=bg3 height="30">
but the odd rows instead of printing
<tr height="30">
it only prints
height="30">
i.e. doesn't print the "<tr" and the empty string. If the project is re-build in JDeveloper, that fixes the situation. My problem is that now the same happened on the Oracle App Server deployment, and I cannot force it to compile the JSP properly.
Any suggestions?
Thanks.

Well I found out how to get EL to be ignored:
<%@ page contentType="text/html; charset=UTF-8" isELIgnored="true" %>
but output is now
+hello ${name}+
when before it was
hello
*So the tag is receiving the template text, but it's not evaluating the ${name} parameter.*
Reading the J2EE Tutorial, I don't think I'm doing anything wrong - but I obviously am! anyone shed any light, even a suggestion?
I'm using Tomcat 5.5 and servlet 2.4
"When used to specify a fragment attribute, the body of the jsp:attribute element can contain only static text and standard and custom tags; it cannot contain scripting elements"
"JSP fragments can be parametrized via expression language (EL) variables in the JSP code that composes the fragment. _The EL variables are set by the tag handler, thus allowing the handler to customize the fragment each time it is invoked_"
