RestDataSource giving me an empty dynamic form?

[wz2b]

Hi,

I am following the "Master Detail" sample and trying to add a detail record section to a working application. For some reason I don't understand I'm getting a completely blank (empty) detail.

The thought I had is: the data from the datasource shows up slowly, is it possible that the DynamicForm looked at it before any data was there?


I create the datasource first

final RestDataSource ds = new RestDataSource();
ds.setFetchDataURL("/test/heard");
ds.setDataFormat(DSDataFormat.JSON);

OperationBinding fetch = new OperationBinding();
fetch.setOperationType(DSOperationType.FETCH);
fetch.setDataProtocol(DSProtocol.GETPARAMS);

ds.setOperationBindings(fetch);

Then I create the grid

final ListGrid grid = new ListGrid();
grid.setCanEdit(true);
grid.setWidth(800);
grid.setHeight(600);
grid.setShowAllRecords(true);
grid.setCellHeight(22);
grid.setAlternateRecordStyles(true);
grid.setDataSource(ds);
grid.setGroupStartOpen(GroupStartOpen.NONE);
grid.setGroupByField("customer");
grid.setAutoFetchData(true);

Then finally the detail form:

final DynamicForm detail = new DynamicForm();
detail.setIsGroup(true);
detail.setGroupTitle("Detail");
detail.setWidth(800);
detail.setHeight(200);
detail.setMargin(15);
detail.setNumCols(4);
detail.setDataSource(ds);

Then finally I add a record click handler. I tried this two ways: one is the way the example does it with .editSelectedData(listGrid), the othe is as you see below. Neither worked:

grid.addRecordClickHandler(new RecordClickHandler() {
	@Override
	public void onRecordClick(RecordClickEvent event) {
		Record r = event.getRecord();

		int platform = r.getAttributeAsInt("platformId");
		status.setContents("Selected record " + platform);
		detail.editRecord(r);
	}
});

When I select a record, the developers console says:

so I don't see any crazy errors in there, debugging is at level INFO right now except for DynamicForm (debug).


Am I on the right general path at least?

Thanks,
