CF9 ORM - One-To-One Mapping, Repeated Column Error
I am looking at the one-to-one relationship, unique foreign key mapping example in the ColdFusion 9 ORM documentation .. http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WS5FFD2854-7F18-43ea-B 383-161E007CE0D1.html#WS606584AD-43B2-48c1-B9E6-69A670694BBB . and I am wondering why the Empolyee.cfc has the primary key defined as EmployeeID whereas the OfficeCubicle.cfc has the primary key defined as id? In most of the other examples, the primary key is just named 'id', so is there something special here that requires the Employee object to have the PK as EmployeeID instead? I have a similar setup defined in a project I am working on, but both objects have their PK named 'id' and I am getting an error that there is a Repeated column in mapping for entity: Response column: id (should be mapped with insert=false update=false). cfcomponent displayname=Response output=false persistent=true extends=com.alagad.PersistentBO hint=A response to a survey cfproperty name=id type=numeric fieldtype=id ormtype=integer generator=native setter=false notnull=true hint=I am the unique identifier for the Response / cfproperty name=prize fieldtype=one-to-one cfc= Prize fkcolumn=id hint=I am the Prize which was (optionally) awarded for this Response / cfcomponent displayname=Prize output=false persistent=true hint=A conference Prize to be awarded to a participant cfproperty name=id type=numeric fieldtype=id ormtype=integer generator=native setter=false notnull=true hint=I am the unique identifier for the Prize / cfproperty name=winningResponse fieldtype=one-to-one cfc= Response mappedBy=prize hint=I am the winning response associated with this prize if it has been awarded / Any ideas?

Re: CF9 ORM - One-To-One Mapping, Repeated Column Error
fkcolumn should specify the name of the foreign key column, not the name of the primary key on the other table. In most cases this attribute shouldn't need to be specified at all, Hibernate will create a column for the foreign key automatically. So either the docs are just badly worded, or they deliberately named the keys differently to try and highlight the difference (as opposed to having both primary keys be named id).
