After experimenting, I have following error:
The code:
// tree
var renamed = this.__pathToItem(path);
try
{
if (renamed)
{
item.remove(renamed);
//renamed.destroy();
//item.remove(renamed);//.destroy(); //remove(renamed);
//item.addAtEnd(renamed);
var pos = 1, ch = item.getItems(false, true);
while (pos < ch.length &&
this.__cmp(ch[pos].getLabel(), toName) < 0 || ch[pos] === renamed)
pos++;
//alert("ADDING TO" + (pos-1));
item.addAtToFolder(renamed, pos - 1);
renamed.setLabel(toName);
}
}
catch (ex)
{
alert(ex.toString());
}
And catched exception is:
Error: Property label of an instance of qx.ui.tree.AbstractTreeElement
is not (yet) ready!
I don't understand it, i'm only removed item and I want to add it on
different place, how I'm doing wrong ?
If I will remove line:
item.remove(renamed);
I have error Too much recursion.
I checked the demos but I don't know what I'm doing wrong:(
