Проблема в настройке разделителя в combo ext js 4.2

Question

Я устанавливаю косую черту (/) в качестве разделителя в комбинации ext js xtype.На вкладке разделитель снова меняется на запятую (,).Это происходит только тогда, когда я выбираю значения из списка.Когда я вставляю значения, разделитель остается косой чертой.

Я использую комбо в сетке ext js.

Любая конкретная причина для такого поведения?
