The easiest way would be to do this with GIN and a provider method.
I'm not sure what the <when-property-is name="alerter"
value="goodbye">, so I could be off base here, but here is a way to do
it.
@Inject
@Provides
public MyResources getMyResources(MyResources hello, GoodByeResources
goodBye, Alerter alerter){
if(alerter.equals("hello")){
return hello;
}else if(alerter.equals("goodbye")){
return goodBye;
}
}
Also, MyResources needs to extend ClientBundle, and then by extendsion
GoodByResources automatically does.
Then you can just @Inject MyResources and it will make the decsion as
to which resource bundle to return.
