Scotty, NH isn't trying to generate the FK on the fly, it is complaining because you have an invalid definition. You must have the same number of columns on both.

In the post about {dynamic-component/} i've asked about the way to store key-value pair in detail-table. [ayende.com/.../...pping-ltdynamic-componentgt.aspx](http://ayende.com/Blog/archive/2009/04/11/nhibernate-mapping-ltdynamic-componentgt.aspx#feedback) I'd like to solve inhertance problem using this key-value princniple. see picture: [tweakers.net/.../full.jpg](http://tweakers.net/ext/f/uWjgoN8WWxwspZKQjxYq0NSf/full.jpg) I want that NHibernate dynamically creates subclasses' attributes using detail-table with key-value pair, where key is the name of the attribute and the value is the value. Is it possible with NHibernate? I prefer this solution over the standard ones (like table-per-subclas or table-per-concrete-class), because i have more than 80 subclasses with three hierarchical levels and all with their specific attributes. Thanks in advance

The mix & match inheritance strategy you mentioned, is it something like this? [knol.google.com/.../11#8](http://knol.google.com/k/fabio-maulo/nhibernate-chapter-8/1nr4enxv3dpeq/11#8)(2E)1(2E)3(2E)(C2)(A0)Table_per_subclass(2C)_using_a_discriminator Thx PS: I'm learning a lot from this article series. Thx for spreading the knowledge.

It let us create a =table per hierarchy= that store all the extra fields on another table, for example. That significantly reduce the disadvantage of using a =table per hierarchy= or table per subclass... There's a typo. Beside this, the post series is awesome :).
