Description

As reported by Stephan Frai:

A servlet does this:

ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(getServletContext());
PwdForgottenJSF pwdForgottenBean = (PwdForgottenJSF) appContext.getBean("pwdForgottenJSF");

web.xml is set up to correctly map a BasicFrameworkAdapter to the current request.

But when pwdForgottenJSF is access-scoped, then this occurs:

SCHWERWIEGEND: Servlet.service() for servlet ControllerServlet threw exception
java.lang.IllegalArgumentException: No AccessScopeManager found.
at ...conversation.AccessScopeManager.getInstance(AccessScopeManager.java:97)
at ...conversation.ConversationAccessLifetimeAspect.markAsAccessed(ConversationAccessLifetimeAspect.java:35)
at ...conversation.spring.SpringConversationScope.notifyAccessConversation(SpringConversationScope.java:194)
at ....conversation.spring.AbstractSpringOrchestraScope.getRealBean(AbstractSpringOrchestraScope.java:333)

The problem is that the AccessScopeManager.getInstance method calls frameworkAdapter.getBean(....), but a BasicFrameworkAdapter has no knowledge of Spring; it just looks up request/session/application scopes.

A possible workaround is for the servlet to manually fetch the AccessScopeManager instance and store it in the request scope.
