Yes, when class ChannelResource is instantiated the algorithm does not
not know anything about the sub-resource method getPopularItems
annotated with @Path("/{channel}/popular/items"), so only path
parameters declared in the @Path of the class are accessible.
Note that there could be many different sub-resource methods each with
different @Path declarations containing different path parameter names.
For fields to work you would need to do something like the following:
@Path("channel/{channel}/")
@Produces("application/javascript")
@PerRequest
public class ChannelResource {
@PathParam("channel") String channel;
@GET @Path("popular/items")
public JSONWithPadding getPopularItems(
@DefaultValue("ever") @QueryParam("timespan") String timespan)
{ ... }
