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');

addFolder2.setControlLink(''); addFolder2.setControlTooltip('Add Folder');

addFolder2.onControlClicked = function(event){alert('addFolder2');};

var delete2 = new AW.UI.Link; delete2.setControlImage('fontsize');
