Question

I have run into a blocking scenario and need help. The problem is basically this:
There is a field on the page which is attached to a validator. This validator in turn validates other fields in particular relation and should throw error messages for all the related fields that have failed validation.

So basically I want a single validator exception to contain multiple facesmessage which should be displayed on the page a list. Is there any method to do the same. From my understanding each ValidatorException can be attached with a single FacesMessage. So I tried out by giving “\n” and even “” in between different messages in a single FacesMessage string to display the messages in new lines but it does not work. Can anyone please help me out?

How about adding the faces messages directly, for example if you had 3 text input fields you wanted to display a message on, and had them bound as input1, input2 and input3:

FacesContext.getCurrentInstance().addMessage(
    input1.getClientId(FacesContext.getCurrentInstance()),
    new FacesMessage(FacesMessage.SEVERITY_ERROR, 
        "Validation Failed", "Validation Failed"));

FacesContext.getCurrentInstance().addMessage(
    input2.getClientId(FacesContext.getCurrentInstance()),
    new FacesMessage(FacesMessage.SEVERITY_ERROR, 
        "Validation Failed", "Validation Failed"));

FacesContext.getCurrentInstance().addMessage(
    input3.getClientId(FacesContext.getCurrentInstance()),
    new FacesMessage(FacesMessage.SEVERITY_ERROR, 
        "Validation Failed", "Validation Failed"));
