• run, login as 'manager'
• go to Project List
• press [Edit] on any project
• change some editable field
• press [Save]
• => Object is still being edited and can not be saved

Sorry, if off-topic for this issue: where can I get some reference to sources of working WPF example applications as complex as ProjectTracker (PT) is (or more) until PT WPF is fixed? (I assume CSLA .NET 5.5.2 is working, just PT WPF is not.) We would like to try CSLA .NET and explore the concepts in some working examples but currently we are not able to find any that's working. Thanks much.
