BeanItemContainer and change beanItem

Hi vaadin team!

Why in BeanItemContainer not provided method for change BeanItem? My problem is that I use a versioning in Enity and after i call
commit
method in Form i save Entity in persistence layer. JPA Provider increment version field by 1, but in BeanItemContainer located BeanItem with old version field value.

It seems reasonable that would be a method that would change BeanItem in container.

Really nobody encountered this type of problem?
