/**
 * @param formatter//from   w w  w .  j av a  2s.  c  om
 */
protected void setFormatterFromTextPane(final DataObjSwitchFormatter formatter) {
    // visit every character in the document text looking for fields
    // store characters not associated with components (jbutton) to make up the separator text

    String text = formatEditor.getText();
    int docLen = doc.getLength();
    int lastFieldPos = 0;

    Vector<DataObjDataField> fields = new Vector<DataObjDataField>();
    //int cnt = 0;
    for (int i = 0; i < docLen; ++i) {
        Element element = doc.getCharacterElement(i);

            // found button at the current position
            // create corresponding field
            String sepStr = (lastFieldPos <= i - 1) ? text.substring(lastFieldPos, i) : "";

            lastFieldPos = i + 1;
            //cnt++;
        }
    }

    // XXX: what do we do with the remaining of the text? right now we ignore it
    // That's because we can't create an empty formatter field just to use the separator... 

    DataObjDataField[] fieldsArray = new DataObjDataField[fields.size()];
    for (int i = 0; i < fields.size(); ++i) {
        fieldsArray[i] = fields.elementAt(i);
    }

    DataObjDataFieldFormat singleFormatter = fieldsArray.length == 0 ? null
            : new DataObjDataFieldFormat("", tableInfo.getClassObj(), false, "", "", fieldsArray);
    formatter.setSingle(singleFormatter);
