JSTL discrepancy?

[Alok Pota]

<c:set var="tooltip" value="${bean.notes}" />
<c:set var="showtext" value="${fn:substring(bean.notes, 0, 60)}..." />

It turns out that fn:substring(bean.notes, 0, 60) mutates the String bean.notes so tooltip also ends up being truncated.

This is different behaviour from scriptlet code..

<%
String tooltip = bean.getNotes();
String showtext = bean.getNotes().substring(0, 60);
%>

In above tooltip will not be truncated (which is the expected behaviour).

Has anyone else seen this or its just a bug in the app server (Resin)?

It works for me running Tomcat 5.
This is the page I put together to test it.

 
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
 
<%!
  public class MyBean{ 
        public String notes; 
  public String getNotes(){ return notes; }
  public void setNotes(String notes){this.notes = notes;}
  }
%>
<%
  MyBean bean = new MyBean();  
  bean.setNotes("This is a string longer than 60 characters just to test out some stuff.  Do you think this is long enough now?");
  request.setAttribute("bean", bean);
%>
<c:set var="tooltip" value="${bean.notes}" />
<c:set var="showtext" value="${fn:substring(bean.notes, 0, 60)}..." />
Text: <c:out value="${showtext}"/><br>
Tooltip: <c:out value="${tooltip}"/><br>

I also do not observe this behavior either under Tomcat 5.0.25 or under Resin 3.0.14.

What version of Resin are you running?
