I'm sure this isn't right, but if I don't select all entities in my catalog, the code generates fine but then it won't compile, because there are relations to the entities that I didn't need.

For example, Inputs is an entity I deleted because I don't need it for this application. But I get this compile error:

C:\Documents and Settings\James Foye\My Documents\LLBLGen Pro Projects\PO\DatabaseGeneric\EntityClasses\AccountClassEntity.cs(314): 'Spinexp.PO.DAL.RelationClasses.AccountClassRelations' does not contain a definition for 'InputsEntityUsingAccountClassID'

This is a known issue and scheduled to be fixed in the current update in development.
