@Inject in @FacesComponent

[ulkgun]

Hello,

We have CDI beans injected in custom components in JSF. In Wildfly 8.2 these were injected properly but after upgrading 9.0 they are not injected anymore.

The issue is similar to How to execute an action when the custom composite component but it is old and Seam related.

I found out it should not be injected and there efforts in JSF 2.3 to make @FacesComponents valid injection targets.

My question is why it was working in 8.2 ? Was it by mistake or was it dropped on purpose?

Thanks

Hi,

In which component do you have injection? Do you have some example? I guess it should work. Where do you find that it should not be injected?

I have a custom jsf tag (endeksSec.xhtml):

<ui:composition ...>

    <cc:interface componentType="com.infina.ops.jsf.tags.comp.dt.EndeksSecTag">

Component class is a faces component:

@FacesComponent("com.infina.ops.jsf.tags.comp.dt.EndeksSecTag")

public class EndeksSecTag extends UINamingContainer {

    @Inject private EndeksServisi es;//<<which is null in 9.0 but OK in 8.2

}

Can you please share or provide some reproducer archive?

Here is the  InjectTest.war - Google Drive

For your previous qustion here is where I found this should not be working : http://jdevelopment.nl/jsf-22/#injection

Unfortunately the ones that perhaps matter most of all, converters & validators, are still not injection targets.

Thank you

I think it's Mojarra bug. I created [WFLY-5057] Could not resolve injected property in custom @FacesComponent - JBoss Issue Tracker. Yes but in your case it's not validator nor converter if I am not mistaken.

Hm the bug was closed as won't fix. It's a bit weird to me but looks like it really worked by accident. You can see comment from Manfred on https://java.net/jira/browse/JAVASERVERFACES-4006

Yes it is a bit unfortunate. It seems we won't upgrade to WF9/WF10 until JSF 2.3 arrives. For workaround, if someone else needs, a utility method with  signature public static T getTyped(Class clazz) can be written into the getter to lookup CDI beans. Thank you Tomas for concern I will mark your answer correct.
