Could not resolve injected property in custom @FacesComponent #4010

Closed javaserverfaces closed 9 years ago

javaserverfaces commented 9 years ago

This looks like Mojarra regression IMO. Having this @FacesComponent:

@FacesComponent("com.infina.ops.tags.TestTag")
public class TestTag extends UINamingContainer {

    public String getHello() {
        return this.getHs().getHello();
    }

    @Inject
    private EquityServiceBizImpl hs;

    public EquityServiceBizImpl getHs() {
        return this.hs;
    }
}

Evaluating TestTag property value results in:

I've experimented on WidlFly 8.2.0.Final vs WildFly 9.0.1.Final. When I used older Mojarra in WildFly 9.0.1 it started to work again.

Affected Versions

[2.2.12, 2.2.11]

@manfredriem said: According to 5.4.1 JSF Managed Classes and Java EE Annotations in JSF 2.2 specification PDF UIComponent is NOT listed as an injection target so @Inject is NOT supported.
