WELD-862 and Seam Cron
by Peter Royle
Hi,
I'm aiming to make a release of Seam Cron available within the next two weeks. Currently there is an outstanding issue (https://issues.jboss.org/browse/WELD-862) which prevents Cron from running properly with Weld. I have been able to carry on developing Cron by testing it against OpenWebBeans, but obviously if we are to release a Seam module it should work against Weld.
It would be nice if WELD-862 could be fixed as soon a possible so that all future versions will work well with Cron.
But more importantly I also probably need to do something special in Cron so that it will work with the version of Weld already deployed in JBoss AS and Glassfish, which will contain the bug. The workaround mentioned in the bug report is to deep copy the InvocationContext. I attempted to do this by serialising and unserialising the InvocationContext but couldn't due to UnserializableExceptions. Does anyone have any advice for me about how I might be able to work around this bug to support existing versions of Weld?
Cheers,
Pete R

CDI 2.0 TCK ObserverMethodWithoutNotifyMethodTest failure - ShouldThrow...Definition or Deployment Exception? - spec inconsistency??
by Gordon Hutchison
Hi Folks,
I work in the IBM CDI implementation team.
We are running the CDI 2.0 TCK/CDS and get a test failure on:
org.jboss.cdi.tck.tests.extensions.lifecycle.broken.observer
Method.ObserverMethodWithoutNotifyMethodTest
that I need some advice on.
The test has:
import javax.enterprise.inject.spi.DeploymentException;
@ShouldThrowException(DeploymentException.class)
// unable to process ObserverMethodConfigurator due to missing notify
method impl
@Test
@SpecAssertions({ @SpecAssertion(section = AFTER_BEAN_DISCOVERY, id =
"ee") })
public void unableToProcessObserverMethodConfigurator() {
}
This behaviour is specified in
https://docs.jboss.org/cdi/spec/2.0/cdi-spec-with-assertions
.html#after_bean_discovery
(search for "ee)" )
ee) If the container is unable to process the ObserverMethodConfigurator it
automatically detects the problem and treats it as a deployment problem.
ObserverMethodWithoutNotifyMethodTest.unableToProcessObserve
rMethodConfigurator()
However what we see coming back from Weld is not a javax
DeploymentException but a javax DefinitionException wrapping a weld
DeploymentException cause
Stack Dump = javax.enterprise.inject.spi.DefinitionException:

So the bottom line is the CDI CTS/TCK test

Have I missunderstood the spec contradiction or missed some part of Weld

What is the best way to pass cofiguration to CDI bean using Weld?
by Alex Sviridov
Hi all
Could anyone suggest solution for the following situation.
Lets suppose we have:
public interface SomeManager{}
@ApplicationScoped
public class SomeManagerImpl implements SomeManager{}
@ApplicationScoped
public class Application {} //application entry point
In Application I need to pass configuration to SomeManagerImpl, but I don't want to
add setConfiguration method to SomeManager interface. What is the best way
to do it in Weld? Maybe I use some CDI mechanisms, or add extra classes. Please, help.
Best regards, Alex Sviridov
