ComboBox items with custom caption

Hi,
I am trying to create a ComboBox where the caption for each item is a combination of properties, like object.title + object.subobject.name
The items that are added to the ComboBox are returned from a backend query wrapped in BeanItem (using LazyQueryContainer).
Is there a way I can set the captions for individual items?

I tried by setting the item caption mode to ITEM_CAPTION_MODE_EXPLICIT and doing comboBox.setItemCaption in the ItemSetChangeListener on both the ComboBox and the Container but that doesn't seem to work
How do I do this? Appreciate any help, thanks.

Hello,

I managed to solve this problem in the following way.

UserContainer is of type BeanItemContainer<UserVO>.

cboxUser = new ComboBox(AppData.getMessage("user"));
cboxUser.setContainerDataSource(AppData.getUserContainer());
cboxUser.setItemCaptionMode(Select.ITEM_CAPTION_MODE_EXPLICIT);
cboxUser.addListener(new ItemSetChangeListener() {

public void containerItemSetChange(ItemSetChangeEvent event) {
UserContainer container = (UserContainer)((ComboBox)event.getContainer()).getContainerDataSource();
Collection<UserVO> users = container.getItemIds();
for (Iterator iterator = users.iterator(); iterator.hasNext();) {
UserVO user = (UserVO) iterator.next();
cboxUser.setItemCaption(user, user.getFirstName() + " " + user.getName());
}
}
});
cboxUser.setInputPrompt(AppData.getMessage("combobox.user"));
cboxUser.setImmediate(true);
cboxUser.setRequired(true);

I hope the example is explicit enough.
