Hi Reto
some more information
In the invocation of writeTo of GenericGraphNodeMBW
public void writeTo(GraphNode node, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
throws IOException, WebApplicationException {
...
}
If accept header is not set
the mediaType param is application/xhtml+xml
and headers.getAcceptableMediaTypes()
returns a list with a single element */* which is then assigned to renderer
what do you suggest to solve this issue?
cheers
