Grid with ComboBox......i don't get it

[Ceene]

Hallo

I searched the whole day in the internet and in this forum but I don't get it. I hope somebody can help me.

I have a Project with a Grid and 3 Cells (name,alter,jaNein). The first and the second cell is a TextField but the third cell is a ComboBox. Till here is everthing all right. I put a List in my ComboBox

 private List<ComboEintrag> getComboEintrag() {
   List<ComboEintrag> plants = new ArrayList<ComboEintrag>();
   plants.add(new ComboEintrag("J", "Ja"));
   plants.add(new ComboEintrag("N", "Nein"));
   return plants;
} 

 ListStore<ComboEintrag> states = new ListStore<ComboEintrag>();
states.add(getComboEintrag()); 

Then I put my data in the Grid

 private List<Plant> getData() {
   List<Plant> plants = new ArrayList<Plant>();
   plants.add(new Plant("Sascha", "29", "J"));
   plants.add(new Plant("Steffi", "24", "N"));
   return plants;
} 

ListStore<Plant> plantList = new ListStore<Plant>();
plantList.add(getData());
 grid = new Grid<Plant>(plantList, new ColumnModel(configs)); 

And now comes my question. How is it possible that in the third cell not the "N" or "J" is written but the "selfValue" from the ComboBox?

I hope my english was not too bad.

@moderator: Sorry for the wrong area, please put me in the right area.

Check this sample:

Basically, all you need to do is prepare the CellEditor for the comboBox case (preProcessValue and postProcessValue).
In the postProcessValue, you will then show the "description" column of your ComboEintrag.
