AW: Binding of h:dataTable and always submit value for input

Hello Helmut, 

bind your dataTable to a 'UIData' componenent attribute instead of 
'HtmlDataTable uiData'. (make a getter and a setter)
---
private UIData table;
----


It works better.

Betreff: Binding of h:dataTable and always submit value for input

Hy,

I have a problem with binding a h:dataTable to a backing bean. After reloading 
I get the message:

09.04.2006 11:13:21 org.apache.myfaces.renderkit.html.HtmlRendererUtils
decodeUIInput
WARNUNG: There should always be a submitted value for an input if it is 
rendered, its form is submitted, and it is not disabled or read-only.

If I am not binding the dataTable everything works well.

Here is the code (I am using MyFaces 1.1.1):

tableBinding.jsp:

<?xml version="1.0" encoding="ISO-8859-1"?>

<jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page";
        xmlns:h="http://java.sun.com/jsf/html";
        xmlns:f="http://java.sun.com/jsf/core";>

        <jsp:directive.page language="java" contentType="text/html; 
charset=ISO-8859-1"
                pageEncoding="ISO-8859-1"/>

<html>
<head>
</head>
<body>
        <f:view>
                <h:form>
                <!--Everything works well, when not using the binding 
attribute-->
                        <h:dataTable binding="#{tableBinding.table}"
                                value="#{tableBinding.values}"
                                var="value">
                                <h:column>
                                        <h:inputText value="#{value.value}" />
                                </h:column>
                        </h:dataTable>
                        
                        <h:commandButton value="Submit" 
action="#{tableBinding.reload}"></h:commandButton>
                </h:form>
        </f:view>
</body>
</html>
</jsp:root>

tableBinding.java:

import java.util.ArrayList;
import java.util.List;

import javax.faces.component.html.HtmlDataTable;

public class TableBinding {
        
        HtmlDataTable uiData;
        ArrayList list = new ArrayList();
        
        public TableBinding() {
                list.add(new Value("first"));
                list.add(new Value("second"));
                list.add(new Value("third"));
                list.add(new Value("fourth"));
                list.add(new Value("fifth"));
        }
        
        public String reload () {
                return null;
        }
        
        public List getValues() {
                return list;
        }
        

        public HtmlDataTable getTable() {
                return uiData;
        }
        
        public void setTable(HtmlDataTable uiData) {
                this.uiData = uiData;
        }

        //Helper Class
        public class Value {
                String value;
                public Value(String s) {
                        value = s;
                }
                public String getValue() {
                        return value;
                }
                public void setValue(String s) {
                        value = s;
                }
        }
        
}

What I'm doing wrong?
Have much thanks for your help!!!!
Helmut
