Andrus Adamchik updated CAY-2964:
---------------------------------
Summary: ClassCastException for non-generated meaningful PKs (was:
ClassCastException for non-generated PKs)
> ClassCastException for non-generated meaningful PKs
> ---------------------------------------------------
>
> Key: CAY-2964
> URL: https://issues.apache.org/jira/browse/CAY-2964
> Project: Cayenne
> Issue Type: Task
> Reporter: Andrus Adamchik
> Assignee: Andrus Adamchik
> Priority: Major
> Fix For: 5.0-M3
>
>
> This was discovered on On adapters that do not support JDBC generated keys
> (Oracle, Firebird, FrontBase and default JdbcAdapter), committing a new
> object whose generated meaningful PK is mapped to an ObjAttribute Java type
> different from the DB column type throws:
> {noformat}
> java.lang.ClassCastException: class java.lang.Integer cannot be cast
> to class java.math.BigInteger
> at ReplacementIdVisitor.updateId(ReplacementIdVisitor.java:106){noformat}
> Root cause: JdbcPkGenerator.generatePk() types the generated value from the
> DB column only (Long for BIGINT, Integer otherwise).
> ReplacementIdVisitor.updateId() then writes it directly into the
> meaningful-PK property without coercion. Adapters using JDBC generated keys
> are unaffected because BatchAction.typeForGeneratedPK() already coerces to
> the ObjAttribute type.
