Description

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
