Sencha ExtJS or Ext-GWT with Vaadin

Hi all,

I’ve searched the forums for this, but it turns up some very old results.

Has anyone tried integrating ExtJS or Ext-GWT (from Sencha) with Vaadin 7?
I’m looking to do this for an intranet application so I can live with the GPLv3 license for ExtJS and Ext-GWT.

Thanks,

John
