JSF checkbox listener

Question

I have a checkbox and a button on my JSF page. I want the button

Answer 1

You need to this by calling a valueChangeListener on ajax call so you can enable/disable button
Here is checkboxes and button

You need create a render class with just one attribute whose value will be set in listener method i-e bean#myChangeListener

public class RenderBean{

    boolean myButton;
    public RendeBean(){

            myButton = true;

    }

    public void enableButton(){

          myButton = true;
    }

    public void disableButton(){

          myButton = false;
    }
}

And here is your bean#myChangeListener

public void myChangeListener(ValueChangeEvent e){
     RenderBean rb = (RenderBean) FacesContext.getCurrentInstance()
            .getExternalContext().getSessionMap().get("renderBean");
        if(e.getNewValue().toString().equals("1"))
                     rb.enableButton();
        else
                     rb.disableButton();
}
