Hi,

I have a problem with ProcedureDataSet it doesn't work and I don't  know 
why?
I work with JBuilder 9 and Postgres 7.4 (Postgres 8.01)

Here is the Quellcode:

row.addColumn("ref", Variant.OBJECT, ParameterType.RETURN);
row.getColumn("ref").setSqlType(Types.OTHER);
row.addColumn("krit", Variant.STRING, ParameterType.IN);
row.setString("krit", "where value=15");

//Error!
db.setAutoCommit(false);
pr.setProcedure(new com.borland.dx.sql.dataset.ProcedureDescriptor(db, "{? = 
call func(?)}", row, true, Load.ALL));
pr.executeQuery();

When I called it with ProcedureProvider it works fine, but I get a 
NullPointerException by db.resultSetToDataSet

ProcedureProvider p = new ProcedureProvider();
p.callProcedure(db, "{:ref = call func(:krit)}", row);
ResultSet rs1 = (ResultSet) row.getObject("ref");

//Error! NullPointerException
StorageDataSet pd=new StorageDataSet();
db.resultSetToDataSet(ds,rs1); //or pd = db.resultSetToDataSet(rs1);

Can anybody help me?
Thanks
