Spring Session not working with Sitemesh - spring

Question

I'm working on implementing Spring Session in a legacy application. I followed the Spring documentation to get the session library implemented and everything seems to be working well, except....
There is a UI element that is decorated on every page through sitemesh. This UI element checks an object in the session to see if it should be displayed or not. When the object is retrieved from the session through the sitemesh decorator, the object is null. When I access the same object through the controller or main content JSP, the object is populated and everything works fine.
In other words:
Web request -> tomcat -> controller -> jsp -> jstl -> session object = ok
then it continues rendering sitemesh decorator adds main.jsp -> jstl -> same session object is null
I think this must be a configuration issue. I can confirm that when I comment out the springSessionRepositoryFilter the page renders correctly, but then I am not using spring session and hitting my redis server. If anyone has any thoughts, I would really appreciate it. Thanks! My web.xml looks like this.

Maybe this can help, where you are using this:
<filter>
<description>sitemesh-filter</description>
<filter-name>MyApplicationSitemeshFilter</filter-name>
<filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>MyApplicationSitemeshFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Try replacing it with this:
<filter>
<filter-name>sitemesh</filter-name>
<filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>sitemesh</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
