--------------------------------------------
Summary: incorrect Unresolved Ambiguous Dependency warning
Key: NETBEANS-5246
URL: https://issues.apache.org/jira/browse/NETBEANS-5246
Project: NetBeans
Issue Type: Bug
Components: javaee - CDI
Affects Versions: 12.2
Environment: Windonws / Netbeans 12.2 / Java OpenJDK 11 / Wildfly 21 /
Weld / Mojarra 2.3.14.SP01
Reporter: Stephen Brooksbank
Attachments: Car.java, CarCatalog.java, CodeCompletion1.png,
CodeCompletion2.png, EL lookup failing.png, IndexController.java, Unresolved
Ambiguous Dependency.png, index.xhtml
I'm getting an "Unresolved ambiguous dependency" warning when I inject a CDI
bean.
!Unresolved Ambiguous Dependency.png!
If I simply ignore the warning message. The application runs correctly and WELD
does not report any issues when the application is deployed.
This issue does not happen always. It appears to be when generics are being
used. In the example above Car.class is a simple POJO. I've got a SessionScoped
CarCatalog.class that @Produces a List<Car>. This reference is sufficient to
make it unique to CDI and should not be causing a warning in NetBeans.
There is a related issue in EL code completion:
!EL lookup failing.png!
If I reference the same CDI object in EL, no code completion is available,
presumably implying no match has been found. Again, if I manually complete the
field and ignore the warning triangles, the code deploys and runs OK.
The suggestions it is generics related, if I use code completion on
h:datatable, I get this for the CDI bean:
!CodeCompletion1.png!
and this if I have a similar field in the backing bean for the page (when code
completion works ok):
!CodeCompletion2.png!
Code samples are attached.
