       Body:
Upon further investigation I've found that moving back to groovy-beta3 fixes the issue.  I have been using the very latest Groovy CVS and it looks like there is a regression of some sort.  I'll close this and report it as a Groovy issue.

Environment: servlet container, scripting of nanocontainer done with Groovy

Description:
When setting up the nanocontainer servlet in web.xml using the context-param "nanocontainer.groovy", it only seems to work for the first container that is configured, or, the first compositionScope.  If any other scope is provided such as a ServletRequest or HttpSession, it fails with the following message...

"Caused by: groovy.lang.MissingMethodException: No such method: buildContainer for class: nanocontainer with arguments: [org.picocontainer.defaults.DefaultPicoContainer-Le89R2mpRr8@public.gmane.org, org.apache.coyote.tomcat5.CoyoteRequestFacade@952905]"

I know it is working the for the first container (in the ServletContext compositionScope) because I print out the compositionScope as soon as the "buildContainer" method is entered and it says...

"compositionScope is: org.apache.catalina.core.ApplicationContextFacade-m6hyCi5e6VU@public.gmane.org"

Here is the script...

class DemoBuilder {
    buildContainer(parent, compositionScope) {
        System.out.println("compositionScope is: " + compositionScope);
        pico = new org.picocontainer.defaults.DefaultPicoContainer(parent)
        if (compositionScope instanceof javax.servlet.ServletRequest) {
            System.out.println("I got here to register a component in the servlet request scope!!!!")
            pico.registerComponentImplementation("util", SomeRequestUtil.class)
        }
        else if (compositionScope instanceof javax.servlet.http.HttpSession) {
            System.out.println("I got here to register a component in the servlet session scope!!!!")
            pico.registerComponentImplementation("counter", SomeCounter.class)
        }
        else if (compositionScope instanceof javax.servlet.ServletContext) {
            //nothing to do for now
        }
        else {
            //nothing to do for now
        }
        return pico
    }
}


Here's the full stack trace....
