             Summary: Fix type parameters ordering in ProcessProducerMethod and ProcessProducerField events
                 Key: CDI-438
                 URL: https://issues.jboss.org/browse/CDI-438
             Project: CDI Specification Issues
          Issue Type: Bug
    Affects Versions: 1.2.Final
            Reporter: Martin Kouba


Since CDI 1.0 there is an inconsistency in the description of {{ProcessProducerMethod}} event...

The text:
{quote}
For a producer method with method return type X of a bean with bean class T, the container must raise an event of type ProcessProducerMethod<T, X>.
{quote}

API:
{code:java}
/**
 * @param <T> The return type of the producer method
 * @param <X> The class of the bean declaring the producer method
 */
public interface ProcessProducerMethod<T, X> extends ProcessBean<X> {
}
{code}

The same applies to {{ProcessProducerField}}. 

TCK and RI (Weld) follow the API. As one of the consequences an {{ProcessProducerMethod<Foo,Producer>}} event is not delivered to an observer with the event parameter {{ProcessBean<Foo>}}.

It's obvious that JCP compatibility rules required to keep the wrong ordering for CDI 1.x (see also the comments in {{javax.enterprise.inject.spi.ProcessProducerMethod}}). I believe this should be fixed in CDI 2.0.
