I'm developing a plug-in to add Serena Dimensions 10 support. I have just started but I've managed to get the global options working. For project configuration I can see the new SCM listed and I can fill the values (even references to the global variables). The DescriptorImpl is called with the correct JSON and I can see the SCM constructor is invoked and populated. The problem is that if I later navigate to the job and click on the Configure link I see the Source Code Management Section blank, the user input was not saved. I must be missing one step in the middle. Anyone can spot the problem?
