Invalid parameter conversion for enums

[emejibka]

Test case
https://github.com/emejibka/nhibernate-fetch-bug/blob/master/TestClass.cs

Insert
INSERT INTO "Product" (Category, Customer_id) VALUES (@p0, @p1); select last_insert_rowid();@p0 = 'SomeCategory' [Type: String (0:0:0)], @p1 = 1 [Type: Int64 (0:0:0)]

Select with fetch
select cast(count(*) as INTEGER) as col_0_0_ from "Product" product0_ where product0_.Category=@p0;@p0 = 1 [Type: Int32 (0:0:0)]

Select without fetch
select cast(count(*) as INTEGER) as col_0_0_ from "Product" product0_ where product0_.Category=@p0;@p0 = 'SomeCategory' [Type: String (0:0:0)]

Why the text enum value is replaced with an integer?

It happens with NH 5.3. 5.2.7 work without issue.
