I accidently misspelled a LocalizationKey in a label control and did not realize it and was getting a NullReferenceException. I think I should of got a KeyNotFoundException.It also happened when I used the MicroFour.StrataFrame.UI.Localization.RetrieveTextValue(TextValueKey) with a key that was not in the XML file. I attached the stack trace.
No big problem, but I though you might want to know.
