Sybase adapter changes?

[Gentry, Michael \(Contractor\)]

I have an application running fine "in production" using Cayenne 1.2M9,
but when testing it locally with Cayenne 1.2 RC1, I get this exception:

Exception = com.sybase.jdbc2.jdbc.SybSQLException: Stored procedure
'getpid' may be run only in unchained transaction mode. The 'SET CHAINED
OFF' command will cause the current session to use unchained transaction
mode.

I didn't make any changes to the Cayenne portion, just twiddled a few
Tapestry bits and was testing the application out.  The error occurs
when I insert a record and need a primary key -- I call a stored
procedure directly using JDBC in my custom PK class (which has been
working perfectly for over a year):

  public Object generatePkForDbEntity(DataNode dataNode, DbEntity ent)
throws Exception
  {
    // Get our connection so we can call the stored procedure
    Connection        connection =
dataNode.getDataSource().getConnection();
    CallableStatement getPID     = connection.prepareCall("{call
getpid(?,?,?)}");

    // Prepare the stored procedure
    getPID.setInt(1, currentBlockSize);            // Slot 1: Number of
PIDs requested
    getPID.registerOutParameter(2, Types.BINARY);  // Slot 2: First PID
allocated
    getPID.registerOutParameter(3, Types.INTEGER); // Slot 3: Number of
PIDs allocated
    try
    {
      // Call the stored procedure
      getPID.execute();
      ...

I get the exception on the execute() line.

I did diffs on the Sybase code, but didn't see any changes -- at least
not since it was converted to Subversion.

Anyone have ideas?

Thanks!
