[Users] variables in filter of LayerContainer loader

[geographika]

Hi,

Where are your themes and theme variables defined? They will need to be 
in the scope of the filter function to work correctly.
Try putting a debugger; statement in to see exactly what is in these 
variables (I'd imagine undefined at the moment).

filter: function(record){
	debugger;
         return (record.get("layer").options.themeId == themes[theme].id);
}


Regards,

Seth
