Could not prevent save action for "Save and Close" command

Hi,

For javascript customization, when we decide to prevent user’s save action after some validations.

It works for “Save” button, but not for “Save and Close” button on create form.

It still continue to close:

SDK reference:

function preventSave(econtext) {

    var eventArgs = econtext.getEventArgs();

    eventArgs.preventDefault();

}
