Oh, I am deeply sorry for the bad format!
I hope you can read it better now:
Hello Gerhard, thanks for the fast answer!
I have an a.view with a commandlink like this:
<h:commandlink action="#{useCaseLinkBean.accessUseCase('foreignUseCase',
aBean")}" />
Then I have the useCaseLinkBean which handles the "routing" between the
usecases with the method:
public String accessUseCase(final String accessLink, final UseCaseCaller
callerBean) {
this.callerBean = callerBean;
return accessLink + "?faces-redirect=true";
}
Now on the b.view I access the aBean in two ways.
The first is an outputText:
<h:outputText value="I came from #{useCaseLinkBean.callerBean}" />
And the second is the back-link via a commandButton:
<h:commandButton
action="#{useCaseLinkBean.callerBean.returnWithResult(bBean.returnObject)}" />
Do I have to access the aBean in some other way to not break the assignement of
aView to aBean instance?
The using of a "routing" bean is not so clever as well. Maybe there is a more
elegant way?
Greetings from Stuttgart,
Steven

>>> I'm using CODI (v 1.0.1) and I'm loving the ViewAccessScope becaue it is
