Yes, I mean DDL Generation dialog you mentioned.
TDM 184.108.40.206 (x86), DB Oracle 11gR2
I click existing action in Model Action, Check comments, close dialog. After I open it again I see no change, button is alway unchecked.
Only thing which changes after this try is diskette in menu to save project.
If I select Run Promtly I see no comments in generated scripts now. Clicking in checkbox doesn’t make change in this.
I tried also " New Action Definition…" Same behavior here, button in dialog is always unchecked.
Difference is in Run Promptly. Generated script always has table and column comments.
