angularjs - ngEnter(ngAnimate) class not getting added in ngDialog -

i don't know if there bug in ngdialog side or there missing not able see ngenter/ngleave class getting added.

my ngdialog rough html template :

<div class ="ng-dialogbg"   ng-swipe-right="swiperight()"   ng-swipe-left="swipeleft()"> <div ng-show="currentid==2" class="canvas-holder" id={{currentid}}>     <avatarcanvas>     </avatarcanvas>  </div>   <div ng-show="currentid==3" class="canvas-holder" id={{currentid}}>     <avatarcanvas>     </avatarcanvas>  </div> </div> 

css :

.canvas-holder.ng-enter{   background-color:blue; } .canvas-holder  .ng-leave{   background-color:black; } 

so testing have used simpler form of code, , don't see ngenter class being added. swipe action changes respective currentid in controller particular div.

ps : have used ngswipe, nganimate in project, modules have been added properly. on ngdialog part or missing someting?
