1. Error messages not being displayed
1) Try to wrap your h:messages into a4j:outputPanel. Because when you are using ajax re-rendering your h:messages may not be re-rendred with other elements.
2) If your message should be displayed after the navigation or a4j:outputPanel does not work for you, post your code, please.

2. Error messages not being displayed
Thank you for you assistance Ilya. Unfortunately the a4j:outputPanel did not resolve the issue. So I tried a very simple page with nothing more that a button that calls a test backing bean and creates an Error message. But that too does not render. So I've attached my code in hopes that you can identify what it is that I am doing incorrectly.
My page:

public class MessagesTest {

public String calculate(String form) {
String msg = "Test Exception!!";
logger.severe(msg);
FacesMessage message = new FacesMessage(msg, msg);
message.setSeverity(FacesMessage.SEVERITY_ERROR);
FacesContext.getCurrentInstance().addMessage(null, message);
return "failure";
}
}
And again, thank you for your assistance.

3. Error messages not being displayed
1) h:messages won't be re-rendered without a4j:outputPanel or without re-rendering a parent tag for h:messages.
Like this:
a4j:commandButton render="wrap"
<h:panelGroup id="wrap">
h:messages
</...>
2) Only as a matter of interest try to assign a message to particular element on form by id. And see if won't work.

4. Error messages not being displayed
Adding the following:
<h:panelGroup id="global-messages">
<h:messages style="color:red" globalOnly="true"/>
</h:panelGroup>
<a4j:commandButton id="get-estimate-submit" render="global-messages"/>
Resolved the issue. I can now display the global messages. And pertaining to assigning a message to a particular element id, that seemed to work with my ajax calls when I would specify a validator. I guess that is because the validator is supplied the component and each of my components on the page has an <h:message> associated with it. Those messages always render next to the component that they are associated with. The only issue I seemed to have was with the global messages but I guess that was due to the fact that I am using an <a4j:commandButton> rather than an <h:commandButton>.
Thank you so much for resolving my issue!!
