Resetting component after validation error

Question

i have created a custom validator class to do some logic whether the input field matches field requirements. I would like that the entered valued be displayed in the field, instead of it being blank. here's what i came up with, but it doesn't appear to work as expected...

    public void validateId(FacesContext context, UIComponent component, Object value)
{
    String id = (String)value;

    if (!(id.length() == 0 || id.length() == 9))
    {
        ((UIInput)component).setValid(false);
        FacesMessage message = new FacesMessage();
        message.setDetail("Invalid");
        message.setSummary("Invalid");
        context.addMessage("popup", message);

        ((UIInput)component).setValue(id);
    }
}

And in my JSF page...

<t:inputText id="tid" value="#{tid.id}" rendered="#{empty tid.id}" 
autocomplete="off" validator="#{accessBacking.validateId}"></t:inputText>

What am i missing here?
