I have an app with a Clientdataset and a Firebird database. When I sort columns in an IB_Grid for the firebird dataset I get an error Clientdataset1: Cannot perform this on a closed dataset - then a window that says Clientdataset:Cannot perform this on an open dataset. At this stage I have created the clientdataset nothing more. I am sorting on an IB_Grid for the Firebird datase that theoretically has nothing to do with my clientdataset. Does anyone know what is happening here.
