In GXT 2, I used CheckBoxGroup to group many CheckBoxes in one field and had a custom validator to check that at least of the checkboxes is checked.
CheckBoxGroup is not in GXT 3, how do I do the same? I studied FieldLabel, AbstractValidator, CheckBox documents, but can't find a concrete example to help me put them together. Appreciated if anyone could point me in the right direction.
