willem Jiang commented on CXF-739:
----------------------------------
the test case that you raised fails for me. It really stems from a
problem with expectations about how wrapped mode should work. You're
operating in unwrapped mode. Which means that the expression in the brackets
{} is mapped to the field on the first parameter. That is, instead of this:
@HttpResource(location = "/topics/{id}")
public String getTopics(@WebParam(name = "id") long id)
You actually want to do this:
@HttpResource(location = "/topics/{id}")
public String getTopics(GetTopics getTopics)
The first one will work in wrapped mode. The second one will work in
unwrapped mode.
