When I attempt to create a template from a masterfile that I've already setup on my file system, I browse to the file and then the system forces me to enter a name for the template (it's a required field). The bug is that it gives me an error that there's a "Duplicate Name" and I can't continue. However if I cancel and return to Templates the Template was actually created.
As a request, I'd like to be able to actually define the name of the template to something other than the name of the .master file, but right now this isn't possible.
In addition as I've mentioned in another post, it's not really a bug but an error in the Documentation. It seems wrong to me that the default location the system looks for a .master file is ~/App_Master but the documentation tells you to create this folder under App_Data/Sitefinity/etc... Either the documentation should be fixed or the location the system looks for .master files by default should reflect your documentation.
