Curly Generics Question

Subject: Curly Generics Question

I've been working with generics for quite a while (and quite like them) but this one has me stumped!

public WORequest createRequest(String method,String url,String anHTTPVersion,Map<String,? extends List<String>> someHeaders,NSData content,Map<String,Object> someInfo) { ... someHeaders.add("foo", Collections.<String>singletonList("bar")); ... }

This causes a compile error "The method add(String,List<String>) is undefined for the type Map<String,capture#1-of? extends List<String>>". Any help appreciated!

cheers.
