DataSource locationDS = LocationGwtRpcDataSource.getInstance();

ListGridField type = new ListGridField("locationType");
type.setWidth(50);
ListGridField location = new ListGridField("name");

item.setWidth(200);
item.setOptionDataSource(locationDS);
item.setValueField("id");
item.setDisplayField("name");
item.setPickListWidth(350);
item.setPickListFields(type, location);


final ListGridField location = new ListGridField("locationName");
location.setEditorType(item);
location.setWidth(item.getWidth());
location.setCanEdit(true);



location.addEditorExitHandler(new EditorExitHandler(){

@Override
public void onEditorExit(EditorExitEvent event) {

if (event.getNewValue() != null) {
Object i = item.getSelectedRecord().getAttribute("id");
}
}
});

it is giving below error...Please let me know how to solve this.

setEditorType is only used to configure the "properties" of the editor, and you cannot use it later in code as a "live" FormItem instance by calling methods on it.

Hi,
Thanks very much for your reply..I tried following thing also..still getting the same issue..

item.addChangedHandler(new ChangedHandler() {
public void onChanged(ChangedEvent event) {
SelectItem obj = (SelectItem)event.getSource();
Integer codi = obj.getSelectedRecord().getAttributeAsInt("id");

}
});

Please help me in solving this..

Thanks

Post in detail what you're trying to accomplish. The dependent selects sample in showcase might help you.

Hi,
I am having an issue when selecting data in selectitem. I attached selectitem to the listgrid field. For the select item i added value field and display field seperately. Initially when loading the data in selectitem shows correctly(shows the name), but when I edited the record, changed the value in selectitem..then the listgridfield shows the "id"(setValueField("id")) but not "name"( setDisplayField("name");)

Please let me know how can I solve it.
