Sometimes after a restart of the JBoss Server, accessing our Seam based application results in a file download dialog instead of the redirection to the 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:

 <h:outputLabel for="rememberMe">Auf diesem Computer merken</h:outputLabel>
</s:decorate>

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

 </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?
