How to check in after phase of Validations phase if validation has failed?

I have written a PhaseListener in which I am checking for the Validations phase. Is there a way using which I can check in the afterPhase() method of listener that validation has failed and the next phase after the Validation phase will be Render Response phase.

If you're on JSF 2.0, just use FacesContext#isValidationFailed() to check it.

if (context.isValidationFailed()) {
    // Validation has failed.
}

You can by the way also check for it in the view side as follows:

<h:panelGroup rendered="#{facesContext.validationFailed}">
    <p>Validation has failed.</p>
</h:panelGroup>

Use the maximum severity for error in the FacesContext

Severity maximumSeverity = FacesContext.getCurrentInstance().getMaximumSeverity();
boolean validationFailed=false;
if (maximumSeverity != null
        && (maximumSeverity==FacesMessage.SEVERITY_ERROR || maximumSeverity
            ==FacesMessage.SEVERITY_FATAL)) {
    validationFailed=true;
}

If the value of the validationFailed is true then there are some error messages present.

How about using FacesContext, can you check if there are any enqueued messages? Eg.

FacesContext context = FacesContext.getCurrentInstance();
Iterator<FacesMessage> messages = context.getMessages();

hope that helps.
