I can use getBinder().getView() as argument for WrongValueException(Component c, String message) to show validation messages on a zul by throwing WrongValuesException. Does MVVM approach have something like that using no wire components? I've seen some examples using modal window and vmsgs, pointing each "property" on zul but I'd like to show validation messages just like default MVC: top-left-corner, appending all messages.
Hello psinalberth,
This may work for you in order to create a custom message:

You may use Clients.wrongValue method like this
public abstract class NotificationValidator implements Validator {
@Override
public void validate(ValidationContext ctx) {
Component component = ctx.getBindContext().getComponent();
String message = getValidationMessage(ctx);
if (StringUtils.isNotEmpty(message)) {
ctx.setInvalid();
Clients.wrongValue(component, message);
} else {
Clients.clearWrongValue(component);
}
}
protected abstract String getValidationMessage(ValidationContext ctx);
it show validation message the same way as WrongValueException
