Generate code for associations

I am currently trying the Professional Edition (build 20030915e).
I cannot generate code for associations. I looked at the Code/Java/Options dialog box, the code generation settings seem to be OK (the "Generate Associations checkbox is checked).
The checkboxes in the “Selected classes for code engineering” always appear as un-checked: my settings are lost each time I close this dialog box. Is it related ???

Is it a limitation in the trial version ?



Oops, my associations were unnamed. Naming them solved the problem. But nevertheless, the Code generation Options dialog box doesn’t match the screenshot in the documentation, there is no “Generate unnamed associations”.
I’m now looking in the doc at how to choose the Java type used for an association.

Best regards,
