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');
delete2.setControlLink(''); delete2.setControlTooltip('Delete');
delete2.onControlClicked = function(event){alert('delete2');};
var obj2 = name2 + addFile2 + addFolder2 + delete2;

var name3 = new AW.UI.Label; name3.setControlText('test doc.txt (HEAD)');
var view3 = new AW.UI.Link; view3.setControlImage('search');
view3.setControlLink(''); view3.setControlTooltip('View');
view3.onControlClicked = function(event){alert('view3');};
var modify3 = new AW.UI.Link; modify3.setControlImage('favorites');
modify3.setControlLink(''); modify3.setControlTooltip('Update');
modify3.onControlClicked = function(event){alert('update3');};
var delete3 = new AW.UI.Link; delete3.setControlImage('fontsize');
delete3.setControlLink(''); delete3.setControlTooltip('Delete');
delete3.onControlClicked = function(event){alert('delete3');};
var obj3 = name3 + view3 + modify3 + delete3;

var name4 = new AW.UI.Label; name4.setControlText('Revision 12');
var view4 = new AW.UI.Link; view4.setControlImage('search');
view4.setControlTooltip('View'); view4.setControlLink('');
view4.onControlClicked = function(event){alert('view4');};
var revert4 = new AW.UI.Link; revert4.setControlImage('favorites');
revert4.setControlLink(''); revert4.setControlTooltip('Revert');
revert4.onControlClicked = function(event){alert('revert4');};
var obj4 = name4 + view4 + revert4;

var name5 = new AW.UI.Label; name5.setControlText('param.txt (HEAD)');
var view5 = new AW.UI.Link; view5.setControlImage('search');
view5.setControlLink(''); view5.setControlTooltip('View');
view5.onControlClicked = function(event){alert('view5');};
var modify5 = new AW.UI.Link; modify5.setControlImage('favorites');
modify5.setControlLink(''); modify5.setControlTooltip('Update');
modify5.onControlClicked = function(event){alert('modify5');};
var delete5 = new AW.UI.Link; delete5.setControlImage('fontsize');
delete5.setControlLink(''); delete5.setControlTooltip('Delete');
delete5.onControlClicked = function(event){alert('delete5');};
var obj5 = name5 + view5 + modify5 + delete5;

var name6 = new AW.UI.Label; name6.setControlText('Revision 11');
var view6 = new AW.UI.Link; view6.setControlImage('search');
view6.setControlTooltip('View'); view6.setControlLink('');

    document.write(tree);

I hope you can find the problem.

up any idea?
