[TurboGears] HTML table rows not adding properly in firefox

[Javier Rojas]

Hi, list

I want to have a widget like a multiplerepeatwidget, but with the possibility of add more widgets. It gets a list of widgets (fields), and creates a table with as many rows as repetitions, each row having one of the widgets I got on the "fields" list. It has too an "add row" button, .... to add new rows :P

the problem I have is that it works fine in Opera and IE, but id doesn't in firefox. When I add a new row, the submit button of the form (which is below the widget) doesn't move down. This is happening in both firefox 2.0 and 1.5.

the code below is the widget source code. The function that add the new row is called "add_increment_row", and it gets an ID to identify the table to be modified


class  RepeatingFields( wdg.RepeatingFieldSet):
  """repite un conjunto de widgets varias veces

  recibe un parámetro repetitions, entero,
  y una lista de widgets, el conjunto de widgets a replicar
  """
  template="""
  <table xmlns:py="http://purl.org/kid/ns#" id="${field_id}_div">
  <tr><td>
  <table id="${field_id}">
    <tr>
      <th py:for="" in fields" class="fieldlabel" py:content="field.label"></th>
    </tr>
    <tr py:for="" in repetitions">
      <td py:for="" in fields">
          <span py:strip="True" py:content="field.display(value_for(field), **params_for(field))"/>
          <span py:if="error_for(field)" class="fielderror" py:content="error_for(field)" />
          <span py:if="field.help_text" class="fieldhelp" py:content="field.help_text" />
      </td>
    </tr>
  </table></td>
  <td valign="bottom"><input type="button" id="${field_id}_adder" value="A&ntilde;adir"/></td>
  </tr>
  </table>
  """
  def __init__(self, *args, **kw):
    super(RepeatingFields, self).__init__(*args, **kw)

    code = wdg.JSSource("""

function clone_increment(obj) {
 MochiKit.DOM.removeEmptyTextNodes(obj);
 field =obj.firstChild;

 new_field = field.cloneNode(true);
 regex = RegExp('[0-9]+');
 num = parseInt(regex.exec(field.id));
 num = num +1;
 parts_id = field.id.split(regex);
 parts_name = field.name.split(regex);
 new_field.id = parts_id[0] + num.toString() + parts_id[1];
 new_field.name = parts_name[0] + num.toString() + parts_name[1];
 return new_field;
}

function add_increment_row (id_table) {
 table = MochiKit.DOM.getElement(id_table);
 actual_ctr = table.rows.length;
 last_row = table.rows[actual_ctr - 1];
 MochiKit.DOM.removeEmptyTextNodes(last_row);
 objs = map(clone_increment, last_row.cells);
 objs = map(partial(TD, null), objs);
 nrow = table.insertRow(-1);
 appendChildNodes(nrow, objs);
}
        """)
    self._javascript_ = [code]

thanks for your help
