Bug or Limitation? ListGrid.groupBy does not show displayField

[atomatom]

I am using the nightly build (3 days old) of SmartGWTEE.

I wanted to use the groupBy feature of the ListGrid to group items by their type. My records contain a typeId, but I want to show the typeName. The example below shows the issue and I attach a screenshot.

What I had hoped was that groupBy would use the displayField, but the group title ignores this. In the screenshot, I expected the group to be the typeName "Value" not "100".

		

                DataSource ds = new DataSource();
		ds.setID("ds");
		DataSource ds2 = new DataSource();
		ds2.setID("ds2");
		{
			DataSourceTextField keyField = new DataSourceTextField("key");
			keyField.setPrimaryKey(true);
			DataSourceTextField valueField = new DataSourceTextField("value");
			ds2.addField(keyField);
			ds2.addField(valueField);
			ds2.setClientOnly(true);
			Record testRecord = new ListGridRecord();
			testRecord.setAttribute("key2", "100");
			testRecord.setAttribute("value", "Value");
			ds2.setTestData(new Record[] { testRecord });
		}
		{
			DataSourceTextField keyField = new DataSourceTextField("key");
			keyField.setPrimaryKey(true);
			DataSourceTextField valueField = new DataSourceTextField("key2");
			valueField.setForeignKey(ds.getID() + ".key2");
			ds.addField(keyField);
			ds.addField(valueField);
			ds.setClientOnly(true);
			Record testRecord = new ListGridRecord();
			testRecord.setAttribute("key", "1");
			testRecord.setAttribute("key2", "100");
			ds.setTestData(new Record[] { testRecord });
		}
		ListGrid grid = new ListGrid();
		grid.setDataSource(ds);
		grid.setAutoFetchData(true);

		ListGridField key2Field = new ListGridField("key2");
		key2Field.setDisplayField("value");
		key2Field.setOptionDataSource(ds2);
		grid.setFields(new ListGridField("key"), key2Field);
		grid.setGroupByField("key2");

		setSize("100%", "100%");
		addChild(grid);

Hello,

I am also getting the same result, did you ever have any joy sorting it?

I did mention it in a post http://forums.smartclient.com/showthread.php?t=12037 a while ago, but didn't get a response! (Maybe didn't explain myself very well)

Kind Regards
