12.0p client side validation issue with empty fields

[Blama]

Hi Isomorphic,

please see this sample (v12.0p_2018-12-22) where there is no validation error, if you click "Validate" directly after load. IMHO the expression

    validators:[
        {type:"regexp", expression:"^\\d{5}(-\\d{4})?$", 
            errorMessage:"Zip Codes should be in the format ##### or #####-####."}
    ]

makes the field mandatory, but no validation error is generated. Tested with latest Chromium 71.

Best regards

The field is mandatory if it’s marked required. It is not otherwise mandatory.
