Richfaces editable dataTable not setting changed Bean Values

[ravishankar.srinivasan]

I have tried a bunch of suggestions after googling but none has so far worked for me. I am trying to display a simple datatable with editable inputText values in each row. table is being populated from database via a usual List of objects. Here is my xhtml page

Richfaces 4.2.1, JSF 2 mojarra bundled with JBoss 7.1, JDK 1.6

<rich:dataTable value="#{wlScoreBean.scoreList}" binding="#{wlScoreBean.scoreTable}" var="item" id="table" style="width:100%">

          <rich:column>

            <f:facet name="header">PARAM NAME</f:facet>

            <h:outputText value="#{item.paramName}" />

        </rich:column>

        <rich:column>

            <f:facet name="header">Portability Score</f:facet>

             <h:inputText value="#{item.portabilityScore}" />

        </rich:column>

        <rich:column>

            <f:facet name="header">Virtualization Score</f:facet>

             <h:inputText value="#{item.virtualizationScore}" />

        </rich:column>

      </rich:dataTable>

        <br/>

        <h:panelGrid columns="3" id="buttonRow">

            <a4j:commandButton value="Save" render="table" execute="@this" action="#{wlScoreBean.update()}">                   

            </a4j:commandButton>

        </h:panelGrid>

and here is my ManagedBean

package com.redhat.gsso.wlprofiler.beans;

import java.io.Serializable;

import java.util.List;

import javax.annotation.PostConstruct;

import javax.ejb.EJB;

import javax.faces.bean.ManagedBean;

import javax.faces.bean.ViewScoped;

import javax.faces.component.html.HtmlDataTable;

import javax.faces.event.ValueChangeEvent;

import org.richfaces.component.UIDataTable;

import com.redhat.gsso.wlprofiler.entity.WorkloadScore;

import com.redhat.gsso.wlprofiler.services.WorkloadScoreManagerService;

@ManagedBean(name = "wlScoreBean")

@ViewScoped

public class WorkloadScoreBean implements Serializable

{

    private static final long serialVersionUID = 1L;

    private HtmlDataTable scoreTable;

    private List<WorkloadScore> scoreList;

    public void watchScore(ValueChangeEvent e)

    {

        System.out.println("old value="+e.getOldValue() + ", New Value="+e.getNewValue());

    }

    public List<WorkloadScore> getScoreList() {

        return scoreList;

    }

    public void setScoreList(List<WorkloadScore> scoreList) {

        this.scoreList = scoreList;

    }

    @EJB

    private WorkloadScoreManagerService wlScoreManager;

    public HtmlDataTable getScoreTable() {

        return scoreTable;

    }

    public void setScoreTable(HtmlDataTable scoreTable) {

        this.scoreTable = scoreTable;

    }

    public WorkloadScoreBean()

    {

    }

    @PostConstruct

    private void getAllScores()

    {

        this.scoreList = wlScoreManager.getAllScores();

    }

    public void update()

    {

        for (WorkloadScore wls : getScoreList())

        {

            System.out.println(wls.getParamName()+"="+wls.getPortabilityScore()+","+wls.getVirtualizationScore());

        }

        //wlScoreManager.update(workloadScore);

    }

}

Here's all the things I tried. All of them result in only the OLD VALUES being printed to console in the update() method.

1. Changed from rich:dataTable to plain old JSF h:dataTable, same result

2. Bound the dataTable to a Managed Bean property, checked in update() method, old values are being printed here too. I just did a getVlaue() on the UIDataTable object and cast it to List<WorkloadScore>.

The List is supposed to have been updated with changed values from the form, but I do not see it happening. I did make sure to put the MBean in ViewScope.

Hi, the problem is execute setting,

<a4j:commandButton value="Save" render="table" execute="@this" action="#{wlScoreBean.update()}">

</a4j:commandButton>

you should execute at least the datatable, so it maybe @All or @form or datatable Id "table";

[ravishankar.srinivasan]

execute=@this did it! Thanks Dan!

be careful with iteration and inputs! On each (ajax) request, all of them (in the belonging form) will become submitted. Since jboss 7.1 has a limited number of request params (512) you could run into some trouble. I've encountered this behavoir a while ago: 8 editable columns and over 60 rows.
