ja my last name updated JBSEAM-2762:
------------------------------------

    Description: 
NPE occurs in Pages.java line 686 (Contexts.getPageContext() returns null).
My config:
    <page view-id="*">
    	<param name="tnetBackUrl" />
         ...
    </page>

    <exception class="java.lang.Exception">
        <redirect view-id="/error.xhtml">
            <message>Error has occured, please contact administrator</message>
        </redirect>
    </exception>

NPE occurs with such config during postback if uncatched exception was thrown during INVOKE_APPLICATION phase. As a result HTTP 500 is returned.
If normal "get" using s:link is calling the same action which throws the same exception, there is no problem.

problem seems to disapear if following is used instead:
    <page view-id="*">
    	<param name="tnetBackUrl" value="#{redirectManager.backUrl}"/>
         ...
    </page>
where redirectManager is event scoped pojo.
