Hello friends.
I've been following the documentation here: https://ninjatrader.com/support/help...development_ov erview.htm
I'm at a point where I get this error when I click on my menu item in the "New" section: (see attached).
This is the AddOn:
I've search for "name" and "+" in my code to try to float something up, but nothing relevant comes up.
I'm not using a XAML file. I'm opting to do everting in code. I don't care about persistence in the workspace, so took that out as well. The tab would be simple, so took out the create, move, delete options from TabControl.
Google searched point to XML errors and such. I'm VERY much not a UI / FrontEnd sort of person, so all lot of this is a bit new and overwhelming.
Cheers!
