Requality

Если в диалоге Document Selection при обновлении документа (Update Document) выбрать папку, то появляется такой exception:

java.lang.ClassCastException: com.unitesk.requality.nodetypes.DocFolder cannot be cast to com.unitesk.requality.nodetypes.Document

Ожидается, что папку выбрать не дадут вовсе. Например, кнопка Ok будет деактивирована пока не выбран документ.
