[Users] Dynamic Node does not bind to layer

[IT Intern]

Dear Matt,

Hmm this seems like this might be a way for me to go..yet one thing that has
me puzzled is that if I declare my layer to have displayInLayerSwitcher:
false, shouldn't it be that this layer does not append a node to the
containers?  I was just trying to avoid having to have each and every layer
container filter out this one layer, other than that I am actually having
troubles filtering out the layer itself :p

loader:{
                filter: function(record) {
                   //From GeoExt examples...
                    //return record.get("layer").name.indexOf("Tasmania")
!== -1
                   //my attempt
                    return record.get("layer").name != 'Photos'; // :( not
working
                }
            }

Thanks,

elshae
