Hi Reinaldo,
What is the full definition of the table? How is the sequence being invoked?

Starting from 1.2 M1 (and M2 that will be released shortly) you can mark a
column as "auto" or "generated" (the label name is still changing in the
modeler as we are still working on this feature)... This will result in
suppressing this column from INSERT.
However you need to understand the limitation of this approach. When you
insert an object, Cayenne needs to know its ObjectId to be able to
continue handling such object properly after the insert is committed. This
means that whatever value is generated by the DB, it has to be passed back
to Cayenne and matched with the original object.
MySQL and SQLServer support that for "autoincrement" columns via new JDBC3
feature... However I am not aware of other DBs/drivers properly passing
back generated values, so there is no clean way of handling that... I
guess one workaround would be to invalidate and refetch all freshly
inserted objects after commit... Not very efficient though...
