vaadin7 - Vaadin 7 loader during view initialization -

in vaadin 7 application when first time trying access view - vaadin shows spinner , hide it. see blank screen 2-4 seconds(this heavy view) , after vaadin shows application.

how tell vaadin not hide spinner until view built ?

updated

this output information vaadin debug window(url ?debug parameter):

i guess should possible show own spinner first thing in ui.init(), "postpone" rest of lengthy init wrapping in access() method (didn't test this). need @push though.

@push public class myui extends ui {    public void init() {     ... // show spinner here     access(new runnable() {          @override          public void run() {             ... //  lengthy initialization here...          }      });    }  } 

it possible though access kick in rightaway , still blocks initial response spinner. if case, should wrap access once more inside new thread().
