I have a big problem after upgrading to Struts 2.1.6. My application works fine
when using Struts 2.0.11. After upgrading to Struts 2.1.6, the application keep
showing a "Blank Page" randomly (sometimes it happen, and quite often, but no
pattern at all) when struts try to redirect to other action. I'm in devMode =
false, and the log shows an exception like this:

I have made a little adjustment due to an issue in Sitemesh 2.3 PageFilter, you
can see the issue here:
http://jira.opensymphony.com/browse/SIM-151
To fix the sitemesh issue, I have to make a replacement class for default
PageFilter (because struts 2 doesn't support latest Sitemesh 2.4.1), and remove
the code "request.getSession(true);".
The "blank page" I said previously is happening before and after I have created
a new PageFilter, so the changes I've made wont be a matter.
In the test case, I try to login and log out repeatedly, and a blank page keep
shows up (randomly) when try to redirect form login.action to home.action. the
web.xml settings:
<filter>
<filter-name>struts2-prepare</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
</filter>
<filter>
<filter-name>velocity</filter-name>
<filter-class>org.apache.struts2.sitemesh.VelocityPageFilter</filter-class>
</filter>
<filter>
<filter-name>struts2-execute</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2-prepare</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>velocity</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2-execute</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
The login and logout action XML:
<action name="login" class="com.cpssoft.action.menus.general.LoginAction">
<interceptor-ref name="defaultStack" />
<interceptor-ref name="language" />
<result name="input"
type="velocity">/pages/general/login.vm</result>
<result name="success" type="redirect">
${originalUrl}</result>
</action>
<action name="logout" class="com.cpssoft.action.menus.general.LoginAction"
method="logout">
<interceptor-ref name="defaultStack" />
<interceptor-ref name="language" />
<result name="input"
type="velocity">/pages/general/login.vm</result>
</action>
${originalUrl} will be filled with: "/pages/home.action" (See the exception
above).
Any Idea how to fix this issue?
Thx a lot
