[Java-gnome-developer] Help using DataColumnObject

[Manuel L. <man...@co...>]

I have a a tree with the following columns:
	protected DataColumnPixbuf _dataImg;
	protected DataColumnPixbuf _dataStatus;
	protected DataColumnString _dataName;
	protected DataColumnObject _dataEntry;
...
	_dataStatus = new DataColumnPixbuf();
	_dataImg = new DataColumnPixbuf();
	_dataName = new DataColumnString();
	_dataEntry = new DataColumnObject();

	_treeStore = new TreeStore(new DataColumn[] { _dataStatus, _dataImg,
_dataName, _dataEntry });

and setting the value using (This is just an example)
        _treeStore.setValue(result, _dataEntry, new Long(1));

But every time try to get the value back, I'm getting null;

public void treeViewEvent(TreeViewEvent event) {
    TreeIter current = event.getTreeIter();
    Object testing = _treeStore.getValue(current, _dataEntry);
    System.out.println(testing );
}

Is there anything especial I need to to do to make it works ?
