Polymer use in Vaadin/GWT

Hi, 
I'm use Vaadin and GWT (50%/50%) from Eclipse, now I see Polymer Elements and want try in my Project from Client Side (GWT) but I don't untersand main arichitekture of this ? have someone keywords for me ?

ok, I'm try this put in my project but this don't work..... 
- im copy vaadin-gwt-polymer-elements-xxxx.jar in WEB-INF/lib 
- insert in my gwt.xml -> <inherits name="com.vaadin.polymer.Elements"/>

but now I get :
 [ERROR] Errors in 'jar:file:/D:/=PROJEKTE=/workspace_smbar6/SmBar/WebContent/WEB-INF/lib/vaadin-gwt-polymer-elements-1.2.3.0.jar!/com/vaadin/polymer/neon/SlideLeftAnimationElement.java'
         [ERROR] Line 41: JsProperty cannot be resolved to a type
         [ERROR] Line 12: The import jsinterop cannot be resolved
         [ERROR] Line 29: JsOverlay cannot be resolved to a type

seems problem with jsInteropMode from maven !? but I'm dont use maven (vaadin use in eclipse ivy..)..... what is jsInteropMode  ? how I can turn on this ? 
 

1.- you have to depend on gwt-2.8.0-SNAPSHOT
2.- you have to add a new dependency jsinterop-annotations-1.0.0-SNAPSHOT.jar 

you can use as reference pom.xml of these projects:

https://github.com/vaadin/gwt-polymer-elements/blob/master/demo/pom.xml

Hi Manuel,
thanks a lot ! 
I try two day but I get a error after next .... I waiting for next release of GWT and Vaadin :-)

I look maybe I can use Polymer manuell not over jsinterop ....
