                 Key: RF-4473
                 URL: https://jira.jboss.org/jira/browse/RF-4473
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.2
         Environment: JDK 1.6.0_05, JBoss AS 4.2.1, Mojarra 1.2_09-b02-FCS, RichFaces 3.2.2 and 3.2.1
            Reporter: Aimar Tellitu


a4j:commandButton doesn´t show messages in <h:messages> when it's an exception in the actionListener. But with <h:commandButton> the messages are shown.
Here is a simple example:

	<h:form>
		<h:commandButton value="Test with h" actionListener="#{test.throwAbortProcessingException}" />
		<a4j:commandButton value="Test with a4j" actionListener="#{test.throwAbortProcessingException}" />
		<a4j:outputPanel ajaxRendered="true">
			<h:messages/>
		</a4j:outputPanel>
	</h:form>	

And the code of the Managed Bean:

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import javax.faces.event.AbortProcessingException;
import javax.faces.event.ActionEvent;

public class Test {
	
	public void throwAbortProcessingException( ActionEvent event ) {
		addMessage( event, "Message before AbortProcessingException");
		throw new AbortProcessingException();
	}
	
	public void addMessage( ActionEvent event, String message ) {
		FacesContext context = FacesContext.getCurrentInstance();
		String clientId = event.getComponent().getClientId(context);
		context.addMessage( clientId, new FacesMessage("message") );		
	}

}
