Summary: ELParsing fails when an expression with function
contains a dash (minus) on 6.0.2.20 and up
Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: regression
Priority: P2
Component: Jasper

Hello,
There is possibly a regression in the ELParser code on Tomcat 6.0.2.20. The
issue I see works fine on Tomcat 6.0.2.18.
I've also tried on Tomcat 6.0.2.29 and it is still failing.
A JSF application which uses Facelets (with .xhtml files) and a custom tag
which contains an expression with a function call starts to fail in Tomcat
6.0.2.20.
The code snippet from the app is:
------------------
<ui:composition xmlns="http://www.w3.org/1999/xhtml";
xmlns:ui="http://java.sun.com/jsf/facelets";
xmlns:h="http://java.sun.com/jsf/html";
xmlns:f="http://java.sun.com/jsf/core";
xmlns:pre-posttag="http://www.test.com/dash";>
<h:outputText value="testing" rendered="#{pre-posttag:test()}"/>
</ui:composition>
-----------------
The exception thrown is (See caused by section):
====================
Throwable occurred: com.sun.facelets.tag.TagAttributeException: /test.xhtml

I've been narrowing the problem down but I cannot find the appropriate way to
fix this as it's generated code. The issue appears to be caused by the changes
made to the code in this revision:
