bug with 8.X level 4 driver?

Hello,

I currently have a problem with the following statement:

  ppS = dd.createPPStatement();
  ppS.setQueryString(
                   "INSERT INTO sandwich_side (name) VALUES ('pickles');" +
                   "INSERT INTO sandwich ( name, sideid) VALUES('club',
currval('sandwich_side_id_seq'));" +
                   "SELECT currval('sandwich_side_id_seq')");
  Resultset rs = ppS.getPreparedStatement().executeQuery();
  try {
    while( rs.next()) {}
  } catch { SQLException ex1) {
    ex1.printStackTrace();
  }

(This use to work, but updated to 8.X driver (for a unicode issue))
SQLMessage: No results were returned by the query.
Statement: Pooled statement wrapping physical statement INSERT INTO
sandwich_side (name) VALUES ('pickles');INSERT INTO sandwich ( name,
sideid) VALUES('club', currval('sandwich_side_id_seq'));SELECT
currval('sandwich_side_id_seq')
org.postgresql.util.PSQLException: No results were returned by the query.
     at
org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:241)

------------------

So did some searching on the forums, lists, etc.. Changed it to this:
  try
  {
     ppS = dd.createPPStatement();
     ppS.setQueryString(
                   "INSERT INTO sandwich_side (name) VALUES ('pickles');" +
                   "INSERT INTO sandwich ( name, sideid) VALUES('club',
currval('sandwich_side_id_seq'));" +
                   "SELECT currval('sandwich_side_id_seq')");
     ppS.initStatement();  //Prepares the statement.
     ppS.getPreparedStatement().execute();
     if( ppS.getPreparedStatement().getMoreResults())
       rs = ppS.getPreparedStatement().getResultSet();
  }
  catch (SQLException ex1)
  {
    ex1.printStackTrace();
  }

  //ResultSet rs = ppS.getGeneratedKeys();
  try
  {
    while (rs.next()) <-----
    {
      System.err.println("getInt: " + rs.getInt(1));
    }
  }
  catch (SQLException ex) {  ex.printStackTrace(); }

So at the moment I can't get the serial id that was created for this new
insert. The old way with just executeQuery worked great (must be 7.X
driver). I tried several version of the 8.X driver, but all had the same
results.

Anyone have the same results? Doing something wrong?

Thanks much,

Damon
P.S. This is with version 8.0 postgresql server.
