        ddw = editor.DomComponents.getTypes();
	
	 for (let i = 0; i < ddw.length; i++) {
	
	ddq = ddw[i].id;
	editor.DomComponents.addType(ddq, {
    model: editor.DomComponents.getType(ddq).model.extend({
      defaults: Object.assign({}, editor.DomComponents.getType(ddq).model.prototype.defaults, {
        
        traits: editor.DomComponents.getType(ddq).model.prototype.defaults.traits.concat([
          'hallo'
        ])
      })
