JBuilder 4 QDS problem - Mailing list pgsql-jdbc

Hi,

Anyone using the Query Dataset that JBuilder 4.0 provided? I am using PostgreSQL 7.2 with the latest JDBC driver, I
defineda table with some NUMERIC fields, e.g. NUMERIC(12,4). When I use the qds to get the data from database, it has
noproblem. But when I want to save the data using the qds, it cannot run with success. The qds will detect a wrong
fieldtype for the numeric field and save fail. The program is working on DB2 with related JDBC driver. Anyone can
help?

The exception:
com.borland.dx.sql.dataset.ResolutionException: An error occurred deleting a row in the "po_hdr" table,
RmiDbOperation.java:449(2002-02-03 12:01:58,310)
