Illegal Model Reference

Okey, I can understand it might seem a bit illegible, I'll try to be a little more spesific. I'm new to JSF as you might understand. I can't post the whole managed bean because it's really to large. As I wrote in the last post, I'm using JavaServer Faces v. 1.1, I guess the apache implementation, though I'm running the application on a Bea Weblogic application server. I've also added the Apache myFaces - tomahawk-1.1.3 tag library to the project.

I've simplyfied the form, so it looks like this:

<h:form id="details">

<h:panelGrid rendered="#{outboundBean.dataItem.meldingstype == 'CertificateIssuedNotification'}" columns="2" columnClasses="header, noStyle, noStyle">

<h:outputText value="#{bundle['Date']}" styleClass="header"/>

<h:inputText readonly="#{outboundBean.dataItem.status == 'Sent'}" value="#{outboundBean.dataItem.date}" id="date"/>

<h:outputText value="#{bundle['Id']}" styleClass="header"/>

<h:inputText value="#{outboundBean.dataItem.localId}" readonly="true" id="id"/>

<h:outputText value="#{bundle['BriteId']}" styleClass="header"/>

<h:inputText readonly="#{outboundBean.dataItem.status == 'Sent'}" value=" #{outboundBean.dataItem.briteId}" id="briteId"/>

<h:outputText value="#{bundle['CompanyType']}" styleClass="header"/>

<h:inputText readonly="#{outboundBean.dataItem.status == 'Sent'}" value=" #{outboundBean.dataItem.companyType}" id="companyType"/>

<h:outputText value="#{bundle['CompanyREID']}" styleClass="header"/>

<h:inputText readonly="#{outboundBean.dataItem.status == 'Sent'}" value=" #{outboundBean.dataItem.companyREID}" id="companyREID"/>

<h:outputText value="#{bundle['CompanyName']}" styleClass="header"/>

<h:inputText readonly="#{outboundBean.dataItem.status == 'Sent'}" value=" #{outboundBean.dataItem.companyName}" id="companyName"/>

<h:outputText value="#{bundle['NewBRId']}" styleClass="header"/>

<h:inputText readonly="#{outboundBean.dataItem.status == 'Sent'}" value=" #{outboundBean.dataItem.newBRId}" id="newBRId"/>

<h:outputText value="#{bundle['OldBRId']}" styleClass="header"/>

<h:inputText readonly="#{outboundBean.dataItem.status == 'Sent'}" value=" #{outboundBean.dataItem.oldBRId}" id="oldBRId"/>

<h:outputText value="#{bundle['CertificateDocRef']}" styleClass="header"/>

<h:inputText readonly="#{outboundBean.dataItem.status == 'Sent'}" value=" #{outboundBean.dataItem.certificateDocRef}" id="certificateDocRef"/>

<h:commandButton rendered="#{outboundBean.dataItem.status != 'Sent'}" action="#{outboundBean.newCertificateIssuedNotification}" value="Register"/>

</h:panelGrid>

</h:form>

It might also be a useful to know that the same page has more than one form, and that all form's uses the same managed bean, "OutboundBean". It actually got three forms that usually are rendered when you enter the page. One for displaying/editing the dataItem's information, one for deleting the dataItem, and one for changing the dataItem's status field. This can only be done while the status isn't "Sent". If the status is "Sent", only one form is visible, though without the possibility to edit/submit information (only for viewing purposes).

Here is the dataItem class. The different constructors is for different message types. I only focus on one message type here.

import java.util.TimeZone;

import java.util.Calendar;

public class MessageData {

Calendar cal = Calendar.getInstance(TimeZone.getDefault());

String DATE_FORMAT = "dd.MM.yyyy";

java.text.SimpleDateFormat sdf =

new java.text.SimpleDateFormat(DATE_FORMAT);

//outbound messages nodes

private String date = sdf.format(cal.getTime()); // Shared

Data in this form comes from a List (List dataList = new ArrayList();) that is displayed in a Datatable in another page. The List contains objects of the MessageData class. When i click a "View/Edit" button on the row I want to view/edit, it puts the values of that row into the "dataItem" (MessageData dataItem) in the OutboundBean. In example, "outboundBean.dataItem.companyName" should use the get/setCompanyName in the MessageData class.

I've got a problem debugging this, because the method that should be called when I push the commandButton (outboundBean.newCertificateIssuedNotification) is never invoked. Instead I get the error message as I wrote in the last post. Exceptions is never thrown. I hope this was clearer, and that you don't need to see the whole OutboundBean class, because it is kinda large.

That might be the solution, I'll try doing it local, but I might have to wait for the IT-infrastructure department to do the upgrade in the repository.

Beans are already configured as session scope.

I did a little Googling to discover where the error message originates from. Assuming you are using the Sun RI, this error corresponds to the constant com.sun.faces.util.Util.ILLEGAL_MODEL_REFERENCE_ID. I did not find any usages of that in the 1.2 RI, however the 1.1_02 version uses it in com.sun.faces.el.MixedELValueBinding.setValue(). In fact, that method always throws an exception with that error message.

So, I would find out exactly what version of the Sun RI you have and get the sources. Then maybe set a breakpoint at that method to try to discover what is going on.
