Hi All, I am getting this error when my custom backoffice editor starts rendering. What I did to create new editor 1.Create new custom backoffice extension based out of ybackoffice template 2.Created and defined custom xxbackoffice-confi.xml 3.Defined our widgets in new xxbackofficewidgetswidget.xml file 4.Defined new editor in defination.xml My edit is working fine but in consile I am getting this error.

Any suggestion would be highly appreciated.
