Calculated fields are submitted back to the server

Obviously not got the hang on how this all works yet. I just discovered that Calculated Fields (fkCaclulated) are submitted back to the XData server on a


TXDataWebDataset.ApplyUpdates;

This is even if none of Provider Flags are set or ProviderFlag.pfHidden is set. So the following excpetion is raised on the server:

Project VCL_Buzz_XServer.exe raised exception class EInvalidJsonProperty with message 'Property "AttendanceText" does not refer to a known property in type "XData.Default.Attendee"'.

Is this a known thing?

Worked around it for now.

I have tried setting the field to ReadOnly, but that still submits back to the server. 


Is this on the fix list?

Yes, we are investigating the cause and possible solutions for this.
