Hi Offray, As Doru mentioned, without a complete example it is difficult to reproduce and analyze your problem.
For the tree to get updated on node addition or removal, you need to use GLMAnnouncingCollection to group your nodes. Hence, when you add a new node in your announcing collection object, this code comes into effect: updateOn: GLMItemAdded from: #yourself; So, make sure you are using appropriate collection object. usman On Wed, Aug 13, 2014 at 2:19 AM, Offray Vladimir Luna Cárdenas < off...@riseup.net> wrote: > Hi again, > > I'm looking at the code at Updataeble Browser in the Basic Examples and I > have done some small modifications.
