Does editor widget support create feature only?

[StephenLam]

I successfully use "Editor widget with simple toolbar" to create a polygon, which let me create feature, editing existing features' attribute and deleting the features. However, I would like to only allow the editor to create feature and edit it, which means editor is not allowed to edit existing or deleting features. Can I achieve this? I have modified some code but it returns me an error:

TypeError {stack: (...), message: "Cannot read property '_init' of undefined"} "TypeError: Cannot read property '_init' of undefined

Refering to this sandbox, the code is changed as below:

        var waterbodies = new FeatureLayer("http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Hydrography/Watershed173811/FeatureServer...",{

          mode: FeatureLayer.SELECTION_NEW,

          outFields: ['*']

        });
