Vaadin Grid

Hi,

I would like to ask if it is possible to use some kind of rendered for specific column in Grid.

public class MyClass{
  String calculatedValue;
  String value;
}
...

Grid grid = new Grid(); itemBeanItemContainer = new BeanItemContainer<>(MyClass.class, items);
grid.setContainerDataSource(itemBeanItemContainer);g
grid.removeColumn("calculatedValue");

When rendering grid i want to display calculatedValue in column, but when entering edit mode, i would like to see calculatedValue.
What is the best way to solve this problem?

I am using Vaadin 7.7.7

EDIT:
In Vaadin 8.0.0 i was able to achieve this

TextField valueTextField = new TextField();
Binder<MyClass> binder = grid.getEditor().getBinder();
doneBinding = binder.bind(valueTextField, MyClass::getValue, MyClass::setValue);
Grid.Column<MyClass, String> calculatedValue = grid.addColumn(MyClass::getCalculatedValue);
calculatedValue.setCaption("Calculated value");
calculatedValue.setEditorBinding(doneBinding);

But in Vaadin 7.7.7 I havent found way how to specify what I want to bind TextField
 

I found a way how to do something similuar in Vaadin 7.7.7

Grid grid = new Grid();
itemBeanItemContainer = new BeanItemContainer<>(MyClass.class, items);
grid.setContainerDataSource(itemBeanItemContainer);
grid.removeColumn("value");

TextField valueEditor = new TextField();

Grid.Column valueColumn= grid.getColumn("calculatedValue");
valueColumn.setEditorField(valueEditor);

FieldGroup editorFieldGroup = grid.getEditorFieldGroup();
editorFieldGroup.bind(valueColumn, "value");
grid.setEditorEnabled(true);
grid.setEditorBuffered(false);

But unfortunately it doesn't work as expected. When the grid is rendered I can see correctly calculatedValue When i want to edit some value it still works. I can see value, but after saving this row (pressing ENTER in unbuffered mode), and going to check real value, (entering edit mode) i see that empty string is set instead of value I filled.
