I am having problems reverting a project to previous version.
Suppose I created a simple java project called P1 with one java file. Now, when I see this file at the version history I see two versions: The current one and the previous one. In order to return to the previous one I need to choose "Sync to this version" on the graph. When I do that the file on my local pc has the previous version but it is not editable in any way since the edit menu is grayed. On the other hand, if I first check out the file I can't syn to previous version since the file is checked-out. So how can I synchronize a java file to previous version and work on this version at the same time?
