Добрый день!
У меня есть следующий дескриптор экрана:

Во время тестирования добавленных фильтров столкнулся со следующей ошибкой: при нажатии на строку в dataGrid, где свойство selectionMode стоит в значении MULTI, возникает ошибка (на скрине):
Плюс к этому кнопки: Запустить, Остановить и Удалить работают неадекватно: при нажатии на выбранную строку в dataGrid они все должны становиться активными, а сейчас почему-то становятся активными 2 из них, причем рандомно. Плюс фильтры также начинают работать некорректно: при выбранной строчке в dataGrid и выборе одного из условий в компоненте multiSelectComboBox получаю такую ошибку:
Если снять галочку с выбранной записи в dataGrid, все работает нормально.
Ниже дескриптор экрана, который работает без ошибок: фильтров нет, но при нажатии на выбранную строку в dataGrid никаких ошибок не возникает:

Вроде бы в дескрипторе никаких изменений, кроме добавления кастомных фильтров не вносил. Stacktrace ни на какие ошибки в моем коде не указывает:
Caused by: java.lang.ClassCastException: class java.lang.String cannot be cast to class java.util.Collection (java.lang.String and java.util.Collection are in module java.base of loader 'bootstrap')

Ничего не могу понять. Где возникает ошибка? В какой момент?
