This is a big tricky to explain, and I've attached a screenshot. I'm working on localhost and I have a module that loads data via $http get with AngularJS, calling DNN WebAPI. I'm using Services Framework. It's a server error so I don't think it has anything to do with a simple Angular $http get.
So let's say I have my module open on a page, and it's populated with data. I jump over to Visual Studio and make some changes to my code. I re-build in debug mode, and push the assembly to the bin folder.
I then reload my page with the module on it.
I can't reproduce this every time, but every 10 times or so, I get the error that "An item with the same key has already been added." And it seems it has to do with viewstate and the authentication.
I'd like to track this down, but perhaps it's just a random thing when working in development and changing the code, certain things being cached, or perhaps I need to prevent caching at some level.
Thank you for any assistance or ideas you can provide!
