Very strange problem: conversion error

[Fraley, Taylor]

So I'm having a very strange problem.  I have a jsp that's using a
h:selectOneMenu populated by an ArrayList within a bean, which is all
pretty standard.  In one environment, on my desktop PC running Tomcat
5.5, everything works fine.  On my SPARC running the same version of
Tomcat, configured, from what I can tell, identically, I get the
following exception when loading the page:

org.apache.jasper.JasperException: org.apache.jasper.JasperException:
javax.servlet.jsp.JspException: "{2}" Conversion Error setting value
''{0}'' for ''{1}''. 
        
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServle
tWrapper.java:512)
        
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.ja
va:377)
        
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
        
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
        
org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFil
ter.java:144)

I've done some poking around on Google, but haven't found anything
terribly useful.  The two possible explanations I've found (getter for
the ArrayList returning null and a mistype of the managed bean name in
the jsp vs. the faces-config.xml) both don't seem to apply here.  Here
are the relevant snippets of code:

...from faces-config.xml...

<managed-bean>
        <managed-bean-name>TransactionReportBean</managed-bean-name>
        
<managed-bean-class>com.level3.ssid.idd.report.web.TransactionReportBean
</managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

...from the TransactionReportBean...

   public TransactionReportBean()
   {
      availableTimes.add(new SelectItem("0", "12:00 AM"));
      availableTimes.add(new SelectItem("1", "01:00 AM"));
      availableTimes.add(new SelectItem("2", "02:00 AM"));
      availableTimes.add(new SelectItem("3", "03:00 AM"));
      availableTimes.add(new SelectItem("4", "04:00 AM"));
      availableTimes.add(new SelectItem("5", "05:00 AM"));
      availableTimes.add(new SelectItem("6", "06:00 AM"));
      availableTimes.add(new SelectItem("7", "07:00 AM"));
      availableTimes.add(new SelectItem("8", "08:00 AM"));
      availableTimes.add(new SelectItem("9", "09:00 AM"));
      availableTimes.add(new SelectItem("10", "10:00 AM"));
      availableTimes.add(new SelectItem("11", "11:00 AM"));
      availableTimes.add(new SelectItem("12", "12:00 PM"));
      availableTimes.add(new SelectItem("13", "01:00 PM"));
      availableTimes.add(new SelectItem("14", "02:00 PM"));
      availableTimes.add(new SelectItem("15", "03:00 PM"));
      availableTimes.add(new SelectItem("16", "04:00 PM"));
      availableTimes.add(new SelectItem("17", "05:00 PM"));
      availableTimes.add(new SelectItem("18", "06:00 PM"));
      availableTimes.add(new SelectItem("19", "07:00 PM"));
      availableTimes.add(new SelectItem("20", "08:00 PM"));
      availableTimes.add(new SelectItem("21", "09:00 PM"));
      availableTimes.add(new SelectItem("22", "10:00 PM"));
      availableTimes.add(new SelectItem("23", "11:00 PM"));
   }

   public ArrayList<SelectItem> getAvailableCnamOptions()
   {
           return availableCnamOptions;
   }

...from the jsp...

<h:selectOneMenu id="beginHour"
value="#{TransactionReportBean.beginHour}" styleClass="rptSmallInputs">
        <f:selectItems value="#{TransactionReportBean.availableTimes}"/>

</h:selectOneMenu>

Judging by all the hits on Google, it seems to be a pretty common
problem, but I'm sort of stumped on what to do next to figure out the
problem.  Has anyone seen this?  Any pointers?

Thanks,
Taylor
