Explicit validation for af:input components

Here is a simple way to get around with the red box validation that used to appear on af:input Components upon some validation

<af:inputText value="#{row.bindings.<attributeValue>.inputValue}"
 id="it3" validate="#{MyBean.validate}">

and in the MyBean class we have it like

public void validate(FacesContext facesContext, UIComponent uiComponent, Object value) {
        FacesMessage message = new FacesMessage();
        message.setDetail("Some Errror message");
        message.setSummary("Value Error message");
        throw new ValidatorException(message);

what are we doing here..

  • Getting the handle to the FacesMessage by explicitly instantiating it
  • Set the Detail,Summary and Severity for the message
  • Throwing the message as a ValidatorException
