Issue with referencing a ManagedBean

Tue, 08 Aug 2006 12:20:35 -0700

Hi,

I am using Myfaces 1.1.3, with Spring 2.0. When I try to reference a managed bean in my jsp files, I get a StringIndexOutOfBoundsException (String index out of range: -1) thrown. I cannot understand for the life of me why this is being thrown. It bubbles up to the top of the exception stack as a failure in setting a property: javax.faces.el.PropertyNotFoundException: _expression_: '#{FtpSitesPage.siteList}'. Below are some application details, any help would be greatly appreciated.

Regards,
Faisal

Here is my faces-config.xml for the managed bean. I use Springs delegating variable resolver for the managed property, however, I know that this isn't the problem, as the exception gets thrown even if I comment out the managed property part.
    <managed-bean>
        <managed-bean-name>FtpSitesPage</managed-bean-name>
        <managed-bean-class>
            com.warnerbros.mam.saw.jsf.page.FtpSitesPage
        </managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
        <managed-property>
            <property-name>ftpSiteDelegate</property-name>
            <value>>#{ftpSiteDelegate}</value>
        </managed-property>
    </managed-bean>

Here is the jsp page (ftpSites.jsp) where the exception is thrown:
<%@ page language="java" pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core " prefix="f"%>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>

<%
    String path = request.getContextPath ();
    String basePath = request.getScheme() + "://"
            + request.getServerName() + ":" + request.getServerPort()
            + path + "/";
%>
