Eager field validation


Vaadin 8 is proposing eager field validation.

Is there some plan to have that in CUBA at some point ?



Currently, we don’t support eager validation out-of-the-box and it seems that it cannot be implemented right now due to major changes inside of Vaadin. I think we will introduce this type of validation with our next Major release 7.

Now, you can only trigger validation if a user hits Enter or moves focus to the next field if you add ValueChangeListener to a field and call field.validate().
