Trigger validation constraints for empty value

OpenUI5 version: all

Browser/version (+device/version): all

URL (minimal example if possible): https://plnkr.co/edit/l6XtmBXqOtlNFBuK2CtA?p=preview

What is the expected result? There is no way to check all constraints for all/one control in a view. The “hack” to get and set the current value doesn’t work for empty input fields.

What happens instead? noting for empty input fields

Request: Provide a simple api to check a constraints for a list of controls and return a single true/false value: this.getView().validateControls(['inputA','inputB','inputC']) Or trigger it at least for strings with a length of 0

I can’t see the point in copying valdiator.js into every ui5 app.

Form with a mandatory input field can’t use the default validation without a huge junk of custom code. That’s odd and should be changed. And it can’t be done in a elegant way, because validation isn`t triggered for empty fields.

Hi, During data binding a check for empty input fields only happens if it was changed.

As you have already done in the “Validator.js”, you can validate a empty property by fetching the binding: https://openui5.hana.ondemand.com/#/sample/sap.m.sample.InputChecked/code/C.controller.js

jQuery.each(aInputs, function (i, oInput) {
	var oBinding = oInput.getBinding("value");
	try {
		oBinding.getType().validateValue(oInput.getValue());
	} catch (oException) {
		oInput.setValueState("Error");
		bValidationError = true;
	}
});

Unfortunately there are no plans to implement a generic solution to validate multiple (empty) controls.
