I want to prevent editing of record in a table based on "Locked" column. I
made the following code and it works reasonable good.

If I type in the text in one of the columns for locked record, key presses
go to a cell and I can continue editing the single cell. JBuilder copies the
original value back to a cell, when moving to another row or cell.

This will display me two times the validation error dialog (when starting to
edit cell and when focus is lost from the cell).

How to prevent this and really make a row as read only?

  void ProcedureDataSetOstoVrk_modifying(DataSet dataSet) throws Exception {
    if (dataSet.getBoolean("Locked")) {
      throw new ValidationException(ValidationException.UPDATE_NOT_ALLOWED,
        "Record is locked.", dataSet.getColumn("Lukko")
      );
    }
  }
