Sometimes after a restart of the JBoss Server, accessing our Seam based application results in a file save as dialog instead of the rendered login page. Restarting the server again solved this usually.

To get a better understanding whats going on, I activated Charles in my Firefox and get the attached session Infos. The redirect happens and the page data will be send, but the last response is this:

</s:decorate>


<h:commandButton value="Login" action="#{identity.login}"/>


</rich:panel>

</h:form>

</ui:define>
</ui:composition>

As you can see, the server sends the source instead of a rendered page.

Any ideas what's going on? Wich components could be involded with this?
