ComboboxItem as a ListGridField EditorType

[mazzi]

Hi,

I am trying to use a comboboxitem as the editortype for a ListGridField. Below is the code that sets up the comboboxitem editortype for the ListGridField:

                clients = new ComboBoxItem("clientCombo");		
		DataSourceField pk = clientsDS.getField("ID");
		pk.setPrimaryKey(true);
		clients.setOptionDataSource(clientsDS);
		clients.setPickListCriteria(new Criteria("ROLE", "INVESTOR"));
		clients.setValueField("FP_ID");
		clients.setDisplayField("FULL_NAME");
		clients.setFilterFields("FULL_NAME");
		clients.setCompleteOnTab(true);

                pickListProperties.setAutoFetchData(false);
                 pickListProperties.setShowHeader(false);

		clients.setPickListProperties(pickListProperties);
		ListGridField fullName = new ListGridField("FULL_NAME");
		clients.setPickListWidth(280);

		clients.addChangedHandler(new ChangedHandler() {

			public void onChanged(ChangedEvent event) {
				FormItem item = event.getItem();
				DynamicForm form = event.getForm();

				SC.logWarn("valuefield value: " + item.getValue());
				
			}
		});

		setEditByCell(true);
		setEditEvent(ListGridEditEvent.CLICK);
		setAutoSaveEdits(false);
		setConfirmCancelEditing(true);
		ListGridField clientName = getField("USER.FULL_NAME");
		clientName.setCanEdit(true);
		clientName.setEditorType(clients);
		clientName.setFilterEditorType(new TextItem());

I have 2 questions regarding using this usage scenario.

1) When the ComboboxItem.ChangedHandler gets fired, how do I get a reference to the actula ComboboxItem instance that fired he event, so I that can get the SelectedRecord if any off of it. I tried doing event.getItem(), but that only returned a FormItem, not a ComboboxItem. the event.getForm(), and event.getSource() did not help either.

2) It seems that whenever I set the DisplayField as follows:

           clients.setDisplayField("FULL_NAME");

it screws up the criteria setting on the OptionDataSource. More specifically, every time I go into edit mode in the ListGridField, I see requests in the developer console where the criteria is set the FP_ID = "FULL_NAME" value. I don't know why setting the DisplayField value has anything to do with the Criteria setting, which I thought should always be set according to this line of code:

		clients.setPickListCriteria(new Criteria("ROLE", "INVESTOR"));

I am using SmartGWT 2.5 latest nightly build, and IE8 on Windows 7.

Thanks in advance,
Mike

Hi,

Any idea as to what I am doing wrong here, or as to what could be happening here, or a workaround. I am kind of stuck here.

Thanks,
Mike

1) this is due to GWT's lack of support for reflection. You can use

new ComboBoxItem(event.getItem().getJsObj())

.. as a kind of "typecast" to switch to the right type

2) see FormItem.fetchMissingValues

Thanks very much Iso, that worked.
