Date Picker Validation

[delmiranda]

Hi Experts,

I'm trying to validate my form referring this code

https://sapui5.hana.ondemand.com/#/entity/sap.m.Input/sample/sap.m.sample.InputChecked.

All the input are working fine but the date picker is still on error state even I already selected the Date.

here is the XML code

<f:fields>
	<DatePicker id="inputPaidOn" dateValue="{ path : 'paymentModel>/paidOn', type : 'sap.ui.model.type.Date', constraints : { minLength: 1, maxLength: 120 } }" required="true" valueFormat="MMM d, y"/>
</f:fields>

controller

_validateInput: function(oInput) {
	var sValueState = "None";
	var bValidationError = false;
	var oBinding = oInput.getBinding("value");

	try {
		oBinding.getType().validateValue(oInput.getValue());
	} catch (oException) {
		sValueState = "Error";
		bValidationError = true;
	}
	oInput.setValueState(sValueState);
	return bValidationError;
},

onSubmitPayment: function(oEvent) {
	.....
	var oCore = sap.ui.getCore(),
	aInputs = [
		oCore.byId("inputAmount"),
		oCore.byId("inputPaidBy"),
		oCore.byId("inputPaidOn"),
	],
	bValidationError = false;

	// Check that inputs are not empty.
	// Validation does not happen during data binding as this is only triggered by user actions.
	aInputs.forEach(function(oInput) {
		bValidationError = this._validateInput(oInput) || bValidationError;
	}, this);

	if (!bValidationError) {
            //....myOdata create
        }
}

Additionaly when I'm getting error on my console.log (Log-dbg.js)

The given date instance isn't valid. -

Also I'm getting error with my property Binding with "paidOn: null"

FormatException in property 'dateValue' of 'Element sap.m.DatePicker#inputPaidOn': Don't know how to format Date to object

Hint: single properties referenced in composite bindings and within binding expressions are automatically converted into the type of the bound control property, unless a different 'targetType' is specified. targetType:'any' may avoid the conversion and lead to the expected behavior.

you bind to dateValue for datePicker

how this one can work? oInput.getBinding("value");
