Updating a record with an enabled control

Question

i need to implement enabled controls like text area with the following javascript :
document.forms[0].elements.disabled= false;
it works well but when i update records in a form, it always displays an error message from internet explorer: HTTP 404 impossible to find the page .
what can i do ?

Answer 1

Yes, you can extend the AbstractTableModel and write a method for updating a whole block.
lets say you've got a Vector with Float[] arrays as elements to hold a 2D array of Float. The you could write:
      TableModel dataModel = new AbstractTableModel() {
            public int getColumnCount() { return col_names.size(); }
            public int getRowCount() { return data.size();}
            public Object getValueAt(int row, int col) {
               return ((Float)((Float[])data.elementAt(row))[col]).toString();
            public String getColumnName(int col) {
             return ((String)col_names.elementAt(col));
            public Class getColumnClass(int col) {
             return String.class;
            public boolean isCellEditable(int row, int col) {
              return true;
            public void setValueAt(Object aValue, int row, int col) {
               try {
                 Float fv = Float.valueOf((String)aValue);
                ((Float[])data.elementAt(row))[col] = fv;
               } catch (Exception ex) {
            public void setBlock(Float block[][], int row, int col) {
               // copy the Arrays with System.arrayCopy into data
      };PS: I don't know, if the above is correct written, havn't test this. But I hope you can recognize the idea behind it.
