Dear Richfaces users

I experience an update issue in Firefox when using a4j:mediaOutput in conjunction with the reRender attribute of a4j components. In my case I use a a4j:push component to rerender a server-side generated image.

It works fine in IE, but in Firefox the re-rendering of the mediaOutput component fails. Other components are updated without problems.

Here is the code:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:f="http://java.sun.com/jsf/core"
 xmlns:a4j="http://richfaces.org/a4j"
 xmlns:rich="http://richfaces.org/rich">

 <ui:define name="routingOverview">
 <a4j:form eventsQueue="graphUpdateQueue" ajaxSubmit="true">
 <a4j:region id="routingGraphUpdate">
 <a4j:push reRender="routingGraph, lastUpdate" interval="2000"
 eventProducer="#{routingOverview.setAjaxListener}" />
 </a4j:region>
 </a4j:form>
 <h:outputLabel for="lastUpdate" value="Last Update:" />
 <h:outputText id="lastUpdate" value="#{routingOverview.lastUpdate}">
 <f:convertDateTime pattern="dd.MM. HH:mm:ss" timeZone="#{configuration.serverTimezone}" />
 </h:outputText>
 <a4j:outputPanel id="routingGraph">
 <a4j:mediaOutput element="img" session="true" cacheable="false"
 createContent="#{routingOverview.renderRoutingGraph}"
 mimeType="image/png" style="border:0px" />
 </a4j:outputPanel>
 </ui:define>
</ui:composition>

I experience this issue in both Richfaces 3.1.4 GA and 3.1.5 GA. I guess it's a caching problem...

Any help is appreciated! Thanks in advance.
