jsf (richfaces) readonly input text validation [duplicate]

Answer 1

Answering from comment: "Woudn't it be easier to validate it in the jsf page backing bean?" You can do application-level validation on a button click or some similar event. You can do something like this in your backing bean and link it to the event.

public String login(){
        FacesContext context = FacesContext.getCurrentInstance();
        if(**<>**){
            FacesMessage message = new FacesMessage();
            message.setSeverity(FacesMessage.SEVERITY_ERROR);
            message.setSummary("Some Valication check");
            message.setSummary("Some Valication check!!");
            context.addMessage("userForm:firstName", message);//adds validation message for field firstName in form userForm
            return "ERROR";
        }
        return "SUCCESS";
    }

Hope this helped.
