Body
I have a Member Table with fields MemID - Primary Key Business_Name Business_Address Business_Phone I need to make an Employer Class which has properties that come from the same Members Table. EmployerName EmployerAddress EmployerPhone Here is my Employer Mapping <pre><code><hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" auto-import="true"> <class name="Employer, Entities" lazy="true" table="Members" dynamic-update="true"> <id name="MemberID" column="MemID" type="Int64"> <generator class="native" /> </id> <many-to-one name="EmployerAddress" column="Business_Address" class="Address, Entities" lazy="proxy" /> <many-to-one name="EmployerPhone" column="Business_Phone" class="Phone, Entities" lazy="proxy"/> <property name="EmployerName" column="Business_Name" not-null="false" /> </class> </hibernate-mapping> </code></pre> I thought that I could map the Members class like this but I get a "System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary." <pre><code><hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" auto-import="true"> <class name="Member, Entities" lazy="true" table="Members" dynamic-update="true"> <id name="MemberID" column="MemID" type="Int64"> <generator class="native" /> </id> <one-to-one name="EmployerInformation" class="Employer, Entities" lazy="false"/> </class> </hibernate-mapping> </code></pre> Also please note. I can't move the Business Information to another table due to constraints on the current system. Business_Address and Business_Phone are FK to another table that is why they are many-to-one mappings.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
