The h:message/h:messages component is not rendering anything if there is no error message and that's why it cannot be rerendered if there is an error message (this is the most possible reason for your action method not to be invoked). Nest the h:message tag into <a4j:outputPanel ajaxRendered="true"> like this:
<a4j:outputPanel ajaxRendered="true"> <h:message for="addressName" /> </a4j:outputPanel> 2007/3/8, [EMAIL PROTECTED] <[EMAIL PROTECTED]>:
