In "open-services" forum I exposed the same problem, but still I have not get to link a requirement in Doors Next Generation 5.0 (I also have tried with newest versions 5.0.1 and 5.0.2) with a bug of Bugzilla. Once I have added “Bugzilla OSLC adapter” as a “Friend” in Doors Next Generation and configured in “Manage project” of the project area as a provider, then I try to link a bug to a requirement. I select the “Implemented by” link type, and opens the IFrame where should appear the creation or selection dialog of Bugzilla. But, it is empty. In order to see what it is happening I have been debbuging with “Development tools” in Internet Explorer 11. I have seen that DNG does a HTTP GET request to the URL “http://172.17.100.227:8080/OSLC4JBugzilla/services/serviceProviders/1” in order to get the services for the product “1”. As a result of this request, it gets the catalog, but then nothing else happens, there are no more requests.

The catalog:

In the next picture it can be seen this HTTP request (go to the link https://www.dropbox.com/s/0abpngxzncggk0z/HTTP_request_serviceProviders.png?dl=0)

I hope someone can help me.

Thank you
