I'm on Vaadin 7.7 and I switch tables to the grid. Only I can not personalize my cells as I would like. Here I would like to add comboboxes on a column from an arraylist and retrieve the chosen value.

Here's some of my code:

Here I create my IndexedContainer

 IndexedContainer indexedContainer = new IndexedContainer();
 indexedContainer.addContainerProperty("Type de véhicule",String.class,"");

Here I add my items:

 indexedContainer.addItem(listValue);
 indexedContainer.getContainerProperty(listValue,
 key.get(0)).setValue(
 String.valueOf(listValue.get(0)));

Finally I put my object in editable and I use this function to do actions during the backup:

grid.getEditorFieldGroup().addCommitHandler(new FieldGroup.CommitHandler() {
 @Override
 public void preCommit(FieldGroup.CommitEvent commitEvent) throws FieldGroup.CommitException 

 
 @Override
 public void postCommit(FieldGroup.CommitEvent commitEvent) throws FieldGroup.CommitException {

If you have any ideas or suggestions do not hesitate :)

Good night

You could use something like this:

List<String> values = obtainValues();
IndexedContainer container = new IndexedContainer();
//Add other properties...
container.addContainerProperty("comboBox", ComboBox.class, null);
//Do more stuff
ComboBox cb = new ComboBox();
cb.addItems(values);
item.getItemProperty("comboBox").setValue(cb);

And, in grid declaration, you may use an addon that allows grid to render components.

Grid grid = new Grid();
//Even more stuff
grid.setContainerDataSource(container);
grid.getColumn("comboBox").setRenderer(new ComponentRenderer());

To obtain the value of the comboBox:

Item item = container.getItem(itemId);
ComboBox cb = item.getItemProperty("comboBox").getValue();
String value = (String) cb.getValue();

Try this:

grid.getColumn("state").setEditorField(getComboState());

where getComboState is:

private Field<?> getComboState() 
 ComboBox comboBox = new ComboBox();
 comboBox.addItem("approve");
 comboBox.addItem("no-approve");
 comboBox.setImmediate(true);
 comboBox.setNullSelectionAllowed(false);
 return comboBox;
