Out of memory problem with ITLibPlaylist.items.count

Hi,

A few mouth ago, I was working on a project that uses the ITLibrary API and the ITLibPlaylist class to load the music playlists in a tree and get the tracks when a playlist is selected.

Now I'd like to work again on this project but as soon as I try to load the playlists, I have a memory bug.

But I also try to load my playlists and its tracks in a fresh new project and it is working so something in my view has a bug :

Maybe a problem with the links between the UI and the data...

Any idea ?

Thx.
