change into ajax in PrimeFaces

Question

I'm trying to make something that change <h:outputText> into <h:inputText> after clicking on button or link. Somtehing similar to this: How to build "edit" button in JSF and switch between h:outputText and h:inputText but I would like to use PrimeFaces.

I think this would be usefull: http://www.primefaces.org/showcase/ui/inplace.jsf but I would like to make that edit mode fires after clicking on edit button or hyperlink, not after clicking on the text I want to change.

Of course after clicking edit button I would like that change to "accept" button that will allow me to save changes and change inputText into outputText

Not much, I have no idea how to connect inplace with button outside: — WojciechKo, Aug 28 '13 at 07:10

Take a look at this SSCCE, it does what you want.

TestBean.java

package com.mycompany;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.context.FacesContext;

@ManagedBean
@ViewScoped
public class TestBean {

    /**
     * Controls if the input field is available or not
     */
    private boolean editable = false;

    /**
     * The String value you want to edit
     */
    private String value = "Default value";

    /**
     * Changes between the inputText and the outputText
     */
    public void changeEditable() {
        editable = !editable;
    }

    public String getValue() {
        return value;
    }

    public boolean isEditable() {
        return editable;
    }

    /**
     * Definitely saves the value
     */
    public void saveValue() {
        FacesMessage message = new FacesMessage("Value " + value + " saved!");
        FacesContext.getCurrentInstance().addMessage(null, message);
    }

    public void setEditable(boolean editable) {
        this.editable = editable;
    }

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

}
