An equivalent shorter form will be this:
DataObjectUtils.intPkForObject(this));

> id);
> setObjectId(objectId);
Theoretically this should work as Cayenne checks for manual id
changes on commit and does the right thing. The catch is that the old
id is used as a key to look up the registered object in DataContext,
so there may be undesired side effects. A cleaner way may look like
this:
this.objectId.getReplacementIdMap().put(CONTACT_ID_PK_COLUMN, new
Integer(id));
