JCDI Event observer without parameter?

[wangliyu]

Seam2 support observe event without passing any parameters (when all the parameters are in the scoped context, there is no need for passing them again).
JCDI require one and only one @Observer parameter for event observing. Does anybody know how to not passing any parameter and observe event in the JCDI? I'm wondering how to merge the seam2 event observer components into JCDI.

Thanks,

Check the API doc. it said:
@Target(value=PARAMETER)
@Retention(value=RUNTIME)
@Documented
public @interface Observes

why can't say @Target({PARAMETER, METHOD}), so that I can use like this:
@Observe
@SomeQualifier
public void someMethod() {
}
