it is this line
//onBeforeUnload: function() {
// this.appStateManager.saveWabAppState(this.map, this.layerInfosObj);
//}

but if you insert read only layer in editor.json config file, and sets them as read only, displays both read only and write in pop-up window by editing, as the old edition WAB DEV 1.2
