I had understood from a former reply from Dmitry that to be able to feed information into the incoming changes section of the UI , one had to implement (and have it returned by the VCS implementation) the CommittedChangesProvider interface.
I've created an implementation of it, and set breakpoints in all methods, but when debugging the VCS plugin and requesting incoming changes no breakpoints are triggered.
IDEA shows one changelist though, where every file of the project is present with apparently the status "added". I have no idea where this one comes from. It has my Windows user as author, and this is not a valid user on any of the vcses I use.
The reported date may well be the project creation date, not sure of it and it has not comment.
Pressing the refresh button doesn't trigger my CommittedChangesProvider implementation to be called
