How can I trap an exception from Notifier action?

Issue

• My requirement is to read a file in a folder and send it to a FTP server. It also has to correctly notify of status; both success and failure. Below is how I configure my service:

<service category="MyServices" name="NotifyFtpService" description="...">
  ...
  <actions mep="OneWay">
    <!-- Exceptions thrown after this point will bubble up and be trapped by this. -->
    <action name="handle-exception" class="com.esb.sample.actions.ExceptionHandlingAction" />
    ...
    <action name="notify-ftp" class="org.jboss.soa.esb.actions.Notifier">
      <property name="okMethod" value="notifyOK" />
      <property name="destinations">
        <NotificationList type="ok">
          <target class="NotifyFTP">
            <ftp URL="ftp://${ftp.user}:${ftp.password}@${ftp.host}/" filename="${filename}" />
          </target>
        </NotificationList>
      </property>
    </action>
    ...
  </actions>
</service>

• I expect that any failures in NotifyFTP bubble up to the exception handling action (ExceptionHandlingAction) which will then trap the failures, but this is not the case; It continues to process the pipeline and finishes it successfully.
• How should I handle this instead?
