Which version of CBL / SGW platform are you using? This is important because conflict resolution process is different between 1.x and 2.0.
Also, what do you mean by “register” ? Is this a CB document.
If you are on 1.x of platform, then this blog may help you with some relevant background.
Note that in 2.0, we have automatic conflict resolution and that should be available in Beta2 release (DB023) . In 1.x, you can check out this link which provides an example of resolving conflicts on CBL.
Hence the above question.
