Rather than query string, you'd tend to append to the path in Tapestry. I
don't think you can do that with the "page name" string return, though, so
the simplest way is to return a configured page object that can passivate.
public class Results {
Integer value;
public void onActivate(EventContext context) {
if( context.getCount() > 0 )
value = context.get(String.class,0);
}
public Integer onPassivate() {
return value;
}
public Results forValue( Integer value ) {
this.value = value;
return this;
}
}
public class MySearch {
@Inject
private Results resultPage;
public Object onSuccessFromMySearchForm() {
return resultPage.forValue(12345);
}
}
