Pipeline Tool: exception on new/open/import project

[InfiniteProductions]

Using dev snapshot of the pipeline tool, since almost last week, I got this exception when using open (also new or import):

System.NullReferenceException: La référence d'objet n'est pas définie à une instance d'un objet.

Pipeline tool from official MG 3.5.1 build works (fortunately for me).
Projects are build using protobuild for WinDx platform on win7 64b.

Using VS 2015 to debug, I got:
Exception occured in AskOpenProject (MainWindow.cs) method on line:
var result = dialog.ShowDialog(null) == Eto.Forms.DialogResult.Ok;

Comment from Alkher on the forum:

have looked into the code.A call to Init() in MainWindow.cs is missing, so dialog.CurrentFilter = _mgcbFileFilter; filters with a null value... and ShowDialogFails

Thanks for reporting this @InfiniteProductions !

@cra0zy ?

Yup, people on forum are right, I missed adding a Init() to the https://github.com/mono/MonoGame/blob/develop/Tools/Pipeline/Windows/MainView.cs#L39

I think I'll finish the Eto.Froms Main Window for the Pipeline Tool by tomorrow so the fix will be in that.

Thanks @cra0zy !

Has this been fixed? Where can I obtain the updated version?

[harry-cpp]

#4786 fixes it. It's not merged yet.

[ed022]

Pardon my ignorance; I'm new to the Mono and GitHub scenes. Is there an executable update, or do I have to manually build from this code repository?

[harry-cpp]

If you want to test out the PR above, you can grab the installer from the build bot: http://teamcity.monogame.net/viewLog.html?buildId=12315&buildTypeId=MonoGame_PackagingWindows&tab=artifacts&guest=1

Cool, thank you very much! =)

With #4786 merged, this is fixed.
