elFinder

Hello! We made a script which allow to upload 1 or more files to ElFinder 1.6.2.

It works perfectly, but one single problem.
I can't use the window.f[0].elfinder.ui.exec('reload'); fn,
BUT ONLY IF I MAKE A NEW FOLDER
and I don't know why.

I suppose it should be when i call the ElFinder with window.f = $('#finder').elfinder({...}); and I make a new folder, something happens. But I can't figure it.

Please help me in this case. Thanks.
