Well i used that approach before and now I am back to using the same approach. A placholder to that array works great but the problem I had before is coming up again. when I click the folder no data shows up but the data is in the array. If i close it and open it again it shows up. The tree is just not updating for whatever reason. Is there something I need to do to refresh everything?
