RE: [ULC-developer] Error inserting row in Tablemodel

Hi Torsten

Looking at it very briefly, your indices seem very wrong when firing events. Table row indices start at 0, just like list indices!

In your sampe, add should be:

fireTableRowsInserted(getRowCount()-1, getRowCount()-1);

In your sampe, remove should be:
fireTableRowsDeleted(row, row);

If you remove row n, it makes no sense to fire an event saying row rowCount() has been removed.

Subject: [ULC-developer] Error inserting row in Tablemodel

Hello

I tried in a Tablemodel to add a row. I have changed my data array and then i called the fireTableRowsInserted-Method and nothing happens. When i resize the ULCFrame then the line is visible. After this i tried fireTableChanged and this works also fine. What is the problem?

Here is the code of my model

private String[] _columnNames = { "Name", "ident", "Empl. Name", "OID", "lastChangeUser"};

private List _rows = new ArrayList();
private List _oid = new ArrayList();
private List _user = new ArrayList();

public void reload(List lst){
  _rows.clear();
  _oid.clear();
  _user.clear();
  for (int r = 0; r < lst.size(); r ++) {
   User user = (User) lst.get(r);
   fillRowElement(user);
  }
  fireTableDataChanged();
}

public OID getOid(int row){
  return (OID)_oid.get(row);
}

public User getUser(int row){
  return (User)_user.get(row);
}

public void addUser(User user){
  fillRowElement(user);
  //bug in ULC
//  fireTableRowsInserted(getRowCount(), getRowCount());
  fireTableDataChanged();
}

private void fillRowElement(User user){
  String[] row = new String[getColumnCount()];
  row[0] = user.getName();
  row[1] = user.getParentEmployee().getIdentification();
  row[2] = user.getParentEmployee().getPerson().getName();
  row[3] = user.getOid().toString();
  row[4] = ""; //user.getHistory().getLastChangeUser().getName();
  _rows.add(row);
  _user.add(user);
  _oid.add(user.getOid());
}

public void removeUser(int row){
  _rows.remove(row);
  _oid.remove(row);
  _user.remove(row);
  fireTableRowsDeleted(getRowCount(), getRowCount());
}

public void updateUser(User user, int row){
  _oid.set(row, user.getOid());
  _user.set(row, user);
  String[] rowe = (String[])_rows.get(row);
  rowe[0] = user.getName();
  rowe[1] = user.getParentEmployee().getIdentification();
  rowe[2] = user.getParentEmployee().getPerson().getName();
  rowe[3] = user.getOid().toString();
  rowe[4] = ""; //user.getHistory().getLastChangeUser().getName();
  _rows.set(row, rowe);
  fireTableRowsUpdated(row, row);
}

public Object getValueAt(int row, int column) {
  return ((String[])_rows.get(row))[column];
}

public int getColumnCount() {
return _columnNames.length;
}

public int getRowCount() {
return _rows.size();
}

public String getColumnName(int column) {
return _columnNames[column];
}

public boolean isCellEditable(int rowIndex, int columnIndex) {
  if (columnIndex == 2){
   //for date format
   return true;
  }
  return true;

}

public void setValueAt(Object value, int row, int column) {
//  if (column == 0){
//   ((User)modelItems.get(row)).getName();
//  }
//  if (column == 1){
//   ((User)modelItems.get(row)).getParentEmployee().getIdentification();
//  }
//  if (column == 2){
//   ((String[])_rows.get(row))[column] = value.toString();
//  }
//  if (column == 3){
//   ((User)modelItems.get(row)).getOid().toString();
//  }
//  ((String[])_rows.get(row))[column] = value.toString();
//  System.out.println("Modelrow: " + row);
  System.out.println("Value: " + value);
  System.out.println("ValueClass: " + value.getClass().getName());
}

public Class getColumnClass(int columnIndex) {
//  if (columnIndex == 2){
//   return Date.class;
//  }
  return String.class;
}
