I get and Assertion failure (D:\Projects\Delphi\Dac\Source\DatasetManager\DsmClasses.pas, line1997)
When adding more than two calculated fields to a TMyQuery, and the project will not compile. The error recurs when deleting the calculated field. After that, the error occurs for all calculated fields until the D7 session is closed.
Removing the Dataset Manager design package eliminates the problem.
