Hi

A exception stacktrace is displayed in the tooltip when I mouse over a button (see attached image). Does anyone know why?

Yeah, if validation fails, validate() throws an exception. Also commit() calls validate(). Catch the exception to avoid the problem.

Button commit = new Button("Commit");
commit.addListener(new Button.ClickListener() {
    public void buttonClick(ClickEvent event) {
        try {
            form.commit();
        } catch (EmptyValueException e) {
            // A required value was missing
        }
    }
});

See
on-line example
