Description

currently it's supported to observe faces-requests via org.apache.deltaspike.core.api.lifecycle.Initialized and org.apache.deltaspike.core.api.lifecycle.Destroyed

since cdi 1.1 there are annotations with the same name.
to avoid confusion, we can support those annotations optionally (if cdi 1.1+ is available). both cdi 1.1+ annotations require the corresponding scope-annotation as value. since javax.enterprise.context.RequestScoped is supported out-of-the-box and this event is about the faces-request, we have to use javax.faces.bean.RequestScoped.

the benefit is that it's possible to observe faces-requests via std. annotations and it's possible to access the faces-context (which isn't the case with an observer for javax.enterprise.context.RequestScoped).

cdi 1.1+ out-of-the-box support:

    protected void onRequestStart(@Observes @javax.enterprise.context.Initialized(javax.enterprise.context.RequestScoped.class) Object payload) {
        //...
    }

    protected void onRequestEnd(@Observes @javax.enterprise.context.Destroyed(javax.enterprise.context.RequestScoped.class) Object payload) {
        //...
    }

ds observer for cdi 1.0+

    protected void onFacesRequestStart(@Observes @org.apache.deltaspike.core.api.lifecycle.Initialized FacesContext facesContext) {
        //...
    }

    protected void onFacesRequestEnd(@Observes @org.apache.deltaspike.core.api.lifecycle.Destroyed FacesContext facesContext) {
        //...
    }

additional option for cdi 1.1+ introduced by this ticket:

    protected void onFacesRequestStart(@Observes @javax.enterprise.context.Initialized(javax.faces.bean.RequestScoped.class) FacesContext facesContext) {
        //...
    }

    protected void onFacesRequestEnd(@Observes @javax.enterprise.context.Destroyed(javax.faces.bean.RequestScoped.class) FacesContext facesContext) {
        //...
    }
