JSF 2.2将Deltaspike（CDI）windowId注入Bean

Question

I'm currently using JSF 2.2 with Deltaspike. We use the Multi-Window-Handling from Deltaspike to handle separate windows. It works great but in a specific case, we need the window ID.

I am able to read it with: FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("dswid");

Is there a more elegant way, maybe with injection into my bean?

Regards,

Sebastian

Answer 1

You can use Param from OmniFaces. I find it more elegant, but it is a third libary.

@Inject @Param
private String dswid;

Answer 2

If you don't want to add a library, you can also inject the external context.

@Inject private ExternalContext externalContext;
