Pete Muir commented on CDI-334:
-------------------------------
Text for resolving ambiguous dependencies changed to:
{quote}When an ambiguous dependency exists, the container attempts to resolve the
ambiguity. The container eliminates all eligible beans that are not alternatives, except
for producer methods and fields of beans that are alternatives. If:
there is exactly one bean remaining, the container will select this bean, and the
ambiguous dependency is called resolvable.
all the beans left are alternatives with a priority, or producer methods or fields of
beans that are alternatives with a priority, then the container will determine the highest
priority value, and eliminate all beans, except for alternatives with the highest priority
and producer methods and fields of alternatives with the highest priority value. If there
is exactly one bean remaining, the container will select this bean, and the ambiguous
dependency is called resolvable.{quote}
Issues with global enablement of alternatives
---------------------------------------------
Key: CDI-334
URL:
https://issues.jboss.org/browse/CDI-334
Project: CDI Specification Issues
Issue Type: Bug
Components: Beans, Resolution
Affects Versions: 1.1.PFD
Reporter: Jozef Hartinger
Assignee: Pete Muir
Fix For: 1.1.FD
* Section 5.1 last paragraph does not reflect global enablement of alternatives.
* Section 5.1.1 fails to define how @Priority relates to:
** alternative stereotypes
** producers
* Section 5.1.6 does not reflect global enablement of alternatives
Section 5.2.2:
** generally the section needs to take global enablement of alternatives into account
** "If all the beans left are alternatives with a priority, then the container will
select the alternative with the highest priority, and the
ambiguous dependency is called resolvable."
*** there is no guarantee that there is a single alternative with the highest priority.
The spec should define what happens in that case.
*** also, the statement should not only consider "alternatives" but also
producers defined on alternatives
* Section 5.3.1 - same as 5.2.2
* Recommended priority ranges for alternatives should be defined somewhere
