Hi Barbara,
I do not know how to customize the message, but I can tell you how you can make the primary key attributes updateable without receiving such errors.
ADF Faces use the primary key attributes to produce a rowkey that is used as a row ID in a table model. If you modify the value of a primary key attribute of a row in an <af:table> then the ADF Faces could not be able to find that row after that. In our projects we workaround this problem as follows:
1) Define in the EO a "service" primary key consisting of a single ROWID attribute of a datatype oracle.jbo.domain.RowID. Base this attribute on the ROWID pseudocolumn of the corresponding DB table and mark the attribute as "Refresh After Insert";
2) Modify the real primary key to become an alternate key (not in the DB table but in the corresponding ADF Business Components);
3) Mark the RowID attribute as a key attribute in the VO instead of the real primary key attributes.
In this way you will never modify at runtime primary key attributes (from ADF's point of view), so you will never lose the corresponding rowkeys and you will never get such errors. Note, that this approach does not require creation of a surrogate (for example, sequence based) primary key in DB.
