Javascript Client object model, rename folder

Question

Hey am trying to rename a folder inside a Document library, right now i get my item and everything is good but when i try to rename it using set_item('title', 'NewFolderName') it crashes and unwinds the stack.

Is there some kind of documentation that would help us with that ? Should i be doing this on the backend instead of the frontend ?

Working

context = SP.ClientContext.get_current(); 
var iter = folderList.getEnumerator();
iter.moveNext();

var folder = iter.get_current();

 folder.set_item('Title', 'TestTitleRename');
 folder.set_item('FileLeafRef', 'TestTitleRename');
 folder.update();
 context.executeQueryAsync(Success,Failure);

Thanks

Answer 1

As I commented already: ;-)

You have to set not only the "Title" but also the "FileLeafRef".

What exactly is the error you are getting? Can you post your code here?

See the following link on updating a listitem. (The folder is also a list item ultimately)
