Komisches JSF Facets Rendering

Interessant. Facets dürfen nicht mehrere Subelemente haben, sondern nur eines. Das wiederum darf schon mehrere Elemente beinhalten. Langer Rede kurzer Sinn: Das

<rich:tabPanel>
	<rich:tab id="xyz">
		<f:facet name="label">
			<s:fragment>
				<h:outputText value="#{bean.property1}" />
				<h:outputText value="#{bean.property2}" />
			</s:fragment>
		</f:facet>
		...
		Tab Content
		...
	</rich:tab>
</rich:tabPanel>

funktioniert, das

<rich:tabPanel>
	<rich:tab id="xyz">
		<f:facet name="label">
			<h:outputText value="#{bean.property1}" />
			<h:outputText value="#{bean.property2}" />
		</f:facet>
		...
		Tab Content
		...
	</rich:tab>
</rich:tabPanel>

nicht.

How to inject a ManagedBean into a ManagedBean

That's really easy, just use the @ManagedProperty annotation.

A Simple Example:

We got two managed beans, one for logging into the system and storing the user's state, and one for using a shopping cart. We got the LoginController

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

@ManagedBean(name = "loginController")
@SessionScoped
public class LoginController {
	... // Do something...
}

and the ShoppingCartController, where we want to use the LoginController:

import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.SessionScoped;

@ManagedBean
@SessionScoped
public class ShoppingCartController {
	
	// Inject some Enterprise Java bean (has nothing to do with the example)
	@EJB
	private BookingBean bookingBean;

	//Inject the LoginController (that's what we wanted to do )
	@ManagedProperty("#{loginController}")
	LoginController loginController;

	... // do the shopping cart stuff
}

That is easy. If you know how :)
