RE: Custom Table Model.

["Dave Wall" <dawall@xxxxxxxxxx>]

I see your code contains
   getResultSet().last();
   return getResultSet().getRow();

What JDBC driver are you using?  The Toolbox JDBC driver does not support
getRow() after a cursor movement based on the end of the result set (like
last()) until JTOpen 3.0 / V5R2.
