i doubt that, nolayout exception being thrown com.vaadin.client.applicationconnection class below code.

if (onlynolayoutupdates) {                                 profiler.enter("updateconnectorstate @nolayout handling");                                 (string propertyname : statejson.keys()) {                                     property property = statetype                                             .getproperty(propertyname);                                     if (!property.isnolayout()) {                                         onlynolayoutupdates = false;                                         break;                                     }                                 }                                 profiler.leave("updateconnectorstate @nolayout handling");                             }

i'm continuously trying debug code somehow can sure problem, no luck yet. have clue ?

open vaadin debug window addding ?debug url , check there both client , server using same vaadin version. client side still using version 7.3.6.

if have own widgetset in use, must recompile fix problem.
