Problem with selectedItem in Tree

Hi,

I realized a tree which contains objects. Objects are composed of Label and Link. I want when I click on an item that link's Image appear, and all others disappear. In the following code (a bit long but directly available), I have the previous Item selected which stay appear. It seems that a sub function is launched but I don't know what it is.

var name1 = new AW.UI.Label; name1.setControlText('dossier');
var addFile1 = new AW.UI.Link; addFile1.setControlImage('search');
addFile1.setControlText(''); addFile1.setControlTooltip('Add File');
addFile1.onControlClicked = function(event){alert('addFile1');};
var addFolder1 = new AW.UI.Link; addFolder1.setControlImage('favorites');
addFolder1.setControlLink(''); addFolder1.setControlTooltip('Add Folder');
addFolder1.onControlClicked = function(event){alert('addFolder1');};
var delete1 = new AW.UI.Link; delete1.setControlImage('fontsize');
delete1.setControlLink(''); delete1.setControlTooltip('Delete');
delete1.onControlClicked = function(event){alert('delete1');};
var obj1 = name1 + addFile1 + addFolder1 + delete1;

var name2 = new AW.UI.Label; name2.setControlText('test dossier');
var addFile2 = new AW.UI.Link; addFile2.setControlImage('search');
addFile2.setControlText(''); addFile2.setControlTooltip('Add File');
addFile2.onControlClicked = function(event){alert('addFile2');};
var addFolder2 = new AW.UI.Link; addFolder2.setControlImage('favorites');

  I hope you can find the problem.

up any idea?
