problem with selectItem in listgrid

[smartgwtuser]

Hi,
I am having an issue when selecting data from 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 "id"(setValueField("id")) but not "name"( setDisplayField("name");)

Please let me know how can I solve it.


Below is the code that I used to create a selectitem
DataSource locationDS = LocationGwtRpcDataSource.getInstance();

ListGridField type = new ListGridField("locationType");
type.setWidth(50);
ListGridField location = new ListGridField("name");
setWidth(200);
setOptionDataSource(locationDS);
setValueField("id");
setDisplayField("name");
setPickListWidth(350);
setPickListFields(type, location);


Below is the code in ListGrid class..

LocationSelectItem locationSelect = new LocationSelectItem();

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


Thanks,
