Async call - RequestScoped not active exception

[emilyj]

I am trying to run cts with async tests. But I hit

When running CTS the test: org.jboss.cdi.tck.tests.context.request.event.async.RequestScopeEventAsyncTest

Methods: testEventsFired

The following exception is thrown: (See testng-results.xml for the full exception stack)

java.lang.AssertionError: expected [true] but found [false]

    at org.testng.Assert.fail(Assert.java:94)

Do I need to do anything for integration to support the async? Any help is much appreciated!

Hi Emily,

the integrator is expected to call WeldInitialListener.requestInitialized() and requestDestroyed() around request processing in a given thread. For async it means calling requestInitialized() before a servlet is run and requestDestroyed() after the servlet method exits. When the async computation finishes and is dispatched back to the servlet container Weld should receive a new pair of requestInitialized()/requestDestroyed() calls around the execution of the code that is dispatch (that would be because the dispatched code executes in a different thread which needs to be set up and cleaned). What Servlet container are you using? Except for Tomcat all other containers implement this correctly.

Thanks Jozef! I am trying to get Weld to work with WebSphere. I'll use your suggestion to fix the async issue.

Hi Jozef,

It turned out the fix is not trivial as I need to make sure the fix will not violate the Servlet spec. I have raised a jira [WELD-1954] RequestContext, SessionContext are thread local - JBoss Issue Tracker to see whether Weld can do something to make the integration easier.

Thanks

Emily
