Issue/Introduction

How to get the list of the Changesets scoped by project ?

Resolution

First step is to list all of the Changesets. That can be achieved by using Custom List and picking the Chanageset as a type. 

Then use this as a query : 
(SCMRepository.Projects contains "/project/<ProjectOID>") 

You can achieve the same result by using WSAPI URL query:
