Thanks Andrus for the prompt reply,

I think how I was able to generate setter for the PK in Cayenne 3.

1. While reengineering DB schema in modeler, there is a checkbox for
meaningful PK.
2. I checked that one and hence it resulted in setter for PK.

However, in revamped UI of 4.0.M4, this checkbox is chucked out and now
there is a text field which is pretty subtle change and I happen to miss
that. Once I write name of the table in the field, generated model has the
PK as a property.

Now this was fine with single table. If there are multiple tables then Is
a comma separated list of table names a good approach ? or what you
mentioned in point 2 of your previous mail ? ( my bet is on this ).

Regards
Sagar
