Jboss seam custom servlet "No active event context"

I have a jboss seam web service. I map my class of service in web.xml as follows

<servlet>
    <servlet-name>pluginhandler</servlet-name>
    <servlet-class>service.PlugInHandler</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>pluginhandler</servlet-name>
    <url-pattern>/*</url-pattern> 
</servlet-mapping>

I read on the blog that if you use your own servlet in a jboss helmet, you need to add the org.jboss.seam.servlet.SeamServletFilter filter to generate all the necessary contexts that I may need to talk to the seam components

<filter>
    <filter-name>Seam Servlet Filter</filter-name>
    <filter-class>org.jboss.seam.servlet.SeamServletFilter</filter-class>
</filter> 
<filter-mapping>
    <filter-name>Seam Servlet Filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

I have an Action seam component that I am trying to create in a web method, but I continue to get a null pointer exception (when I try to call its method), and the main reason is "There is no context for active events." I attached an exception stack as follows

    Servlet.service() for servlet pluginhandler threw exception
