Here's an example from "GWT Development with Activities and Places" tutorial
(
http://code.google.com/webtoolkit/doc/latest/DevGuideMvpActivitiesAndPlaces.html
)
public class HelloPlace extends Place {
private String helloName;
public HelloPlace(String token) {
this.helloName = token;
}
public String getHelloName() {
return helloName;
}
public static class Tokenizer implements PlaceTokenizer<HelloPlace> {
@Override
public String getToken(HelloPlace place) {
return place.getHelloName();
}
@Override
public HelloPlace getPlace(String token) {
return new HelloPlace(token);
}
}
}
As you correctly guessed, in the constructor you call the "get..." method
and stores it in an attribute, just like you did with the clientFactory.
Then you can check if this attribute is not null in the start method and
call the appropriated method of the view.
