When dealing with ASP.NET MVC you might use hidden fields to pass values of model properties from the view to an action of a controller. So you will find yourself writing something like that in your view:

“The view XXXX or its master was not found” error looks like that:

"The view 'XXXX' or its master was not found or no view engine supports the searched locations. 
The following locations were searched:
~/Areas/XXXX/Views/XXXX/XXXX.cshtml
~/Areas/XXXX/Views/XXXX/XXXX.vbhtml
~/Areas/XXXX/Views/Shared/XXXX.cshtml
~/Areas/XXXX/Views/Shared/XXXX.vbhtml
~/Views/XXXX/XXXX.cshtml
~/Views/XXXX/XXXX.vbhtml
~/Views/Shared/XXXX.cshtml
~/Views/Shared/XXXX.vbhtml"

and I recently had to deal with it, although I was 100% sure that my view was in the right place inside my MVC project.
