Editor widget - validations

MKY

Editing attributes in Editor widget needs an event before applying edit. I have columns that their values depend on another column. I tried Form Constraints and Field calculations in Arcade but they do not work for all scenarios. 

If there is a new event like "before-apply-edit", it will help in validating all columns before posting.

Regars,

That's not a bad idea...you could extend that workaround to include validation like so:

var featureLayer = new FeatureLayer({
	//etc
});

featureLayer.originalApplyEdits = featureLayer.applyEdits;

featureLayer.applyEdits = function(edits, options) {
	var errorMessage = null;

	//validate the values in the edits object; if validation fails, set a string value to the errorMessage variable, for example:
/*
	if (edits.addFeatures[0].attributes.name === "")
		errorMessage = "Name - value required";
*/
	if (typeof errorMessage == "string")
		return Promise.reject(new Error(errorMessage));
	else
		return this.originalApplyEdits.apply(this, arguments);
};
