"No primary key attribute found in class" Error

General Questions/Discussions
1

I’ve created a table ‘test’ with ‘id’ as a key and some other attributes. Then I created a self Many to Many Entity whose primary keys are testid and testid2 from the first table. When I try generating code, I keep getting a “No primary key attribute found in class” Error. The ER diagram clearly shows that the key for the newly generated Entity are there.
And the relationship between the ‘test’ table and the ‘test_test’ table are identifying.
Any help?

Hi Anonymous,

Thank you for your evaluation.

I have tried creating an ERD based on the information you gave, and then generate code from it. However, I am unable to repeat the error you described. I attached my ERD, could you please check if I have drawn it correctly?

Also, could you please try synchronizing the ERD to Class Diagram before generating code? You can do this by right-clicking on the ERD, and then select Synchronize to Class Diagram from popup menu.

Finally, I would like to know which build you are now using. Could you please take a look at the About dialog box (Help | About…) to check the build number?

Looking forward to hearing from you.

Best Regards,
Jick

Jim,
To reproduce the problem. Make sure you add any attribute to the newly created test_test entity. And then try generating the code. I am using DB Architect Evaluation version build 20051204b - I will try downloading the latest eval copy.
