[richfaces-issues] [JBoss JIRA] (RF-11331) FacesMessages not shown when using a4j:commandButton and myFaces

[Brian Leathem (JIRA)]

    [ https://issues.jboss.org/browse/RF-11331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12707941#comment-12707941 ] 

Brian Leathem commented on RF-11331:
------------------------------------

a4j:commandButton does an ajax request by default, and the h:commandButton does a full page submit.  An accurate comparison of the buttons is as follows:

{code}
a4j: <a4j:commandButton value="Show message" actionListener="#{richBean.showMessage}"/>
h: <h:commandButton value="Show message" actionListener="#{richBean.showMessage}">
    <f:ajax execute="@this" render="@from" />
</h:commandButton>
{code}

In which case they behave the same: not rendering the message.

> FacesMessages are not displayed when they are thrown from a a4j:commnandButton action and myFaces 2.0.6/2.0.7/2.1.1 is used, they appear on server console instead.
> Works fine when myFaces 2.0.5 is used or h:commandButton is used instead of a4j:commandButton (any myFaces version).
