Combobox переписал. не найду ошибки арея

[locust19]

Переписал функции combobox для мультивыбора, должно всегда выдавать ареем.. если больше 1 элемента выберешь будет мне арей. если 1 то ни стринг ни бог его знает что.. не могу достать и сообразить, помогите пожалуйста, как исправить?

определенно решение лежит тут

причем очень интересно выходит.. когда данные с dataprovider приходят. то первое поле попадает в арей [0], но увы при выборе одного элемента из бокса ничего не возвращает_ и также выбирает, но стоит для этого нажать сперва ctr и отпустить его с одним выбранным элементом
