[Users] Dynamic Node does not bind to layer

[IT Intern]

Thanks Matt,

I got the right filter ;)

 loader:{
                filter: function(record) {
                    return record.get("layer").name.indexOf("Photos") == -1
                }
            }

Still a little puzzled on why displayInLayerSwitcher: false didn't work out
:-/

But many many thanks, I was stuck on this for awhile...
