Hi Could it be that the Http Service API exists twice in your framework ? And thus your sample bundle and the Web Console and bridge bundles use different API wirings ?
You can cross check in the web console to which bundle a specific package is wired by looking at the details of a bundle and checking the imports (which contains the wire sources) Regards Felix Am 14.03.2013 um 14:35 schrieb Stephan Schröder: >> Can you verify the HttpService is available at all in the framework ? >> (You might try to access the web console) > The web console seems to be available.
