FieldData Test Fail

[netmonster01]

So I have a form #249 it has 1000's of entries, when I run the test case it come back with two FormData objects with null field values. But if I overload using the search string FormId=249 I get back the objects with values.

Fail:
var data = _client.Data.FormData.Get(249);
Assert.Greater(data.fieldValues.Count, 0);

Pass:
var data = _client.Data.FormData.Get(249,"FormId=249", 1,100);
Assert.Greater(data.elements[0].fieldValues.Count, 0);

Is this by design?

Thanks,
KC
