I'm having trouble getting nested datasets working for the first time. Originally I was getting a 'Record changed by another user' message. I created a simple test ap with a grid and 3 client datasets connected via a DCOMConnection to my server. A button sets the main cds params and calls opens it,. The grid displays the results but when I popup either of the 2 nested tables they are empty and don't even have any columns. What am I missing here? --------------------------------------------------------------------------- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz
