Improve managed property error messages

[javaserverfaces]

Consider the following case:

public class BannerBean implements Serializable { private String authDetails = "My Details";

public String getAuthDetails()

{ return authDetails; }

public void setAuthDetails(String authDetails)

{ this.authDetails = authDetails; }

}

Anytime I try to bind the field authDetails to an h:outputText with:

<h:outputText value="#

{banner.authDetails}

"/>

I return the following in my Tomcat log:

javax.faces.el.EvaluationException: javax.faces.FacesException: java.lang.ClassCastException: com.dtn.petro2.petroadmin.common.BannerBean

My backing bean is defined as the following in my faces-config.xml:

Banner banner com.dtn.petro2.petroadmin.common.BannerBean session authDetails My Details

In this case, the ManagedBean implemenation would expect the managed bean to be a Map. If the managedbean is not a Map, as above, then we just throw a ClassCastException with no diagnostics to help the developer fix the issue.

We need to go through the managed bean code and improve the error messages.
