Hi Yishay, no. MX/SPARK had a dataField, so I think that's needed for emulation in MXRoyale. I refer to BASIC. For what I read from Alex while looking at the right way to do labelFunction we talked about "labelField" as the Basic API. But there's a DataFieldProviderBead that, at least in Jewel, was not used at all, and I removed yesterday, still need to track Basic. Since I don't know much more about MXRoyale it is possible that MXRoyale could use dataField from Basic, or that some components in Basic use dataField, in that case maybe there's no mucho to do. But if it was an API introduced at the beginning and now is finally not used we could save some bits and confusion removing it from the code base
