[nhusers] GenericEnumMapper doesn't work in Publish

[Art One]

Hello,

I'm actually upgrading an older Project with nHibernate 5.1.
In this project GenericEnumMapper is used to map values (Ok,
RegistrationPossible, RegistrationInProcess)

Code looks like:
http://orand.blogspot.com/2006/12/generic-nhibernate-enum-string-mapping.html

Everything works great when doing local in Visual Studio but not after
publishing on server - on server we get:

Stack Trace:
[ArgumentException: Requested value 'OK' was not found.]
System.Enum.TryParseEnum(Type enumType, String value, Boolean
ignoreCase, EnumResult& parseResult) +1185
System.Enum.Parse(Type enumType, String value, Boolean ignoreCase) +110
NHibernate.Type.EnumStringType.GetInstance(Object code) +67

[HibernateException: Can't Parse OK as ConServiceStatus]
NHibernate.Type.EnumStringType.GetInstance(Object code) +210



After comparing all settings and configs the last 2 days, I don't know
where to go now.

So thanks in advance for any hint

Just a shot in the dark, but your error says OK, while your enum is Ok.

I don't see any code where you are ensuring that where the Enum.Parse is
setting the ignoreCase flag correctly.

Thank you for the shot - you are right!

In testing database the values are in upper case, not so in local database
and production database. I don't know why this happens in the past (was
before my time) and why nHibernate didn't had problems in earlier version.

Anyway I think an update in my testing database will fix my problem now -
so again thank you.
