In my entity class I have the following property:
public virtual IList<string> Tags { get; private set; }
In my fluent nhibernate mapping file, I have the following mapping:
HasMany(x => x.Tags)
.Table("ProductTags")
.Element("Tag")
.AsBag();
Which results in the following hbm mapping
<bag name="Tags" table="ProductTags">
<key>
<column name="Product_id" />
</key>
<element type="System.String, mscorlib, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089">
<column name="Tag" />
</element>
</bag>
I am able to build a session factory, but when I try to save an
entity, I get the following exception:
NHibernate.MappingException : No persister for: System.String

entityName)
