This has been discussed many times here and in other forums as well.
When a 3rd party SODE jetway works with SODE, but not with GSX, it's usually because the scenery developer has used different names for the jetways compared to their proper names in the AFCAD. While they will still work with SODE only, in order for GSX and SODE to communicate without any doubts which gate is which, the jetway name MUST match 100% the standard used in the AFCAD file.
This won't restrict the ability to show jetways with a more descriptive name, because SODE has a separate parameter for that, which developers should use to specify the name presented to the users, and use the AFCAD name strictly as it is in the AFCAD.
