Updating p:inputText in form

Hello All,

This is my first post to the forum.

I am really struggling to get my head around JSF2, things that worked suddenly will stop working because of a tiny change in some bean

. Any ways, I am posting a test case that is not working as expected for some reason.

The following form

Code: Select all

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    >
<f:view contentType="text/html">
<h:head>
</h:head>

<h:body>

    <h:form id="simpleForm">
                <!-- The id is prepended here-->
        <h:panelGrid id="grid" columns="3">
            Name:
            <p:inputText id="name" value="#{testController.bean.name}" size="40"/>
            <p:message  for="name"/>

            Value:
            <p:inputText id="value" value="#{testController.bean.value}" size="40"/>
            <p:message  for="value"/>

        </h:panelGrid>
        <h:panelGrid id="controls" styleClass="controls" style="height:100%">
            <h:panelGroup styleClass="controls" >

                <p:commandButton
                    id="saveButton"
                    value="Save"
                    actionListener="#{testController.echoBean}"
                    update="simpleForm:grid"/>
            </h:panelGroup>
        </h:panelGrid>
    </h:form>


    <h:form>
            <p:commandButton
                    id="cancelButton"
                    value="Resest"
                    actionListener="#{testController.resetBean}"
                    update="simpleForm:grid"/>
    </h:form>
</h:body>
</f:view>
</html>

Has the following controller

Code: Select all


import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.event.ActionEvent;

/**
 * User: fotis
 * Date: 18/05/11
 * Time: 01:40
 */
@ManagedBean
@ViewScoped
public class TestController {


    private Bean bean;

    public TestController() {
        this.bean = new Bean();
    }

    public Bean getBean(){
        return this.bean;
    }


    public void resetBean(ActionEvent event){
        this.bean = new Bean();
    }

    public void echoBean(ActionEvent event){
        System.out.println("Bean name: "+bean.getName());
        System.out.println("Bean value: "+bean.getValue());
    }
}

Which is managing the following bean

Code: Select all

import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public class Bean{

        @NotNull
        @Size(min=1)
        private String name;

        @NotNull
        @Size(min=1)
        private String value;


        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getValue() {
            return value;
        }

        public void setValue(String value) {
            this.value = value;
        }
    }

1.) I click once without submitting any values, the validation messages show up fine because I am updating "simpleForm:grid"
2.) Enter the value for only 1 of the 2 fields and click "Save" the corresponding message shows up fine in my form
3.) After a failed validation in 1 of the 2 fields, click the "Reset" button, the action is called in the "TestController", the error messages are cleared from the form, the bean values are "null" but the p:inputText to which you have submitted any values for, still remains, and it is not cleared.

I would like to know if this is the expected behaviour, it seems to me that since the Bean values are null, then the p:inputText should not contain any data.

I am eagerly waiting for any replys.

Fotis
