[cdi-dev] [JBoss JIRA] (CDI-334) Issues with global enablement of alternatives
[
https://issues.jboss.org/browse/CDI-334?page=com.atlassian.jira.plugin.sy...
]
Jozef Hartinger reopened CDI-334:
---------------------------------
5.1.1.1 - it is still unclear how @Priority works with @Alternative producers
5.2.2
{quote}all the beans left are alternatives with a priority, then the container will
determine the highest priority value, and eliminate all
beans, *except for producer methods and fields of beans that are alternatives with
priorities*, with other priority values. If there
is exactly one bean remaining, the container will select this bean, and the ambiguous
dependency is called resolvable.{quote}
So if there is an alternative bean with priority 2000 and a non-alternative producer
method defined on an alternative bean with priority 1000 this combination causes an
unresolvable ambiguous dependency?
5.3.1 - still outdated
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
