Those are two different lifecycles that can't be combined. In other words, you can't use the OSGi @Reference annotation to inject services into your @ViewScoped JSF managed bean.<br /><br />When <a href="https://www.jcp.org/en/jsr/detail?id=378">JSR 378</a> is done you will be able to inject the OSGi service using JSR 330 @Inject (via CDI). But for now, you have to use a ServiceTracker approach. I recommend that you study the source in the <a href="https://github.com/liferay/liferay-faces-portal/tree/master/demo/primefaces-users-portlet">primefaces-users-portlet</a> demo. Specifically, look at the <a href="https://github.com/liferay/liferay-faces-portal/blob/master/demo/primefaces-users-portlet/src/main/java/com/liferay/faces/demos/bean/UsersBackingBean.java#L107-L113">postConstruct</a> method of the UsersBackingBean class to see how to acquire/open a ServiceTracker and the <a href="https://github.com/liferay/liferay-faces-portal/blob/master/demo/primefaces-users-portlet/src/main/java/com/liferay/faces/demos/bean/UsersBackingBean.java#L115-L118">preDestroy</a> method to see how to close it. The [url=http:// public void save(ActionEvent actionEvent) { try { if (!userLocalServiceTracker.isEmpty()) {]save method shows how to get the underlying service from the ServiceTracker and then invoke the service.<br />Finally I recommend that you watch my DEVCON presentation titled <a href="https://www.youtube.com/watch?v=z5JkXJeJmmA&t=1383s">Developing WABs with a View to The Future</a> on YouTube. Starting at around 21 minutes into the video, I discuss the ServiceTracker approach.<br />Kind Regards,<br />NeilNeil Griffin2020-03-31T13:54:04ZMoved to the Liferay Faces category.Neil Griffinhttps://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=1188351122020-03-31T13:40:02Z2020-03-31T13:40:02ZMoved to the Liferay Faces category.Neil Griffin2020-03-31T13:40:02ZInjection on managed beanAlex Pasquinihttps://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=1188142862020-03-27T09:45:23Z2020-03-27T09:45:23Z<html><head></head><body>Dear all,<br><br>I'm trying to build a dummy jsf portlet using primefaces which calls a service on the init method.<br>The problem I'm experiencing is that the bean of the service is not injected.
