debug foreign key constraint error - sql-server

Question

I have a Sql Server db that was generated by Nhibernate's schema tool and hitting the error below when I try to enter a known PartyId, and I just do not get the error. (Even tho the log output I'm showing is from a test run using NHibernate, I can replicate the error manually using the SQL Server db that NHib generated)
I think the FK constraint is saying the PartyId must exist first, but like I say - it does.
I have SQL Server 2008 management studio but I rarely use it, preferring to access it through Visual Studio on those rare times I need to. So I have two basic questions
how do I see the ddl in sql server from visual studio?
how do I debug and fix my FK constraint problem?
DDL generated by NHib
create table PartyNames (
PartyNameId INTEGER not null,
PartyId INTEGER not null,
RequiredName TEXT not null,
EverythingElse TEXT,
ContextUsed TEXT,
Salutation TEXT,
EffectiveStart DATETIME,
EffectiveEnd DATETIME,
primary key (PartyNameId)
)
create table Parties (
PartyId INTEGER not null,
Type TEXT not null,
primary key (PartyId)
)
The ERROR

Answer 1

The foreign key is probably not defined correctly. This is the current definition.
ALTER TABLE [dbo].[PartyNames] WITH CHECK ADD CONSTRAINT [Party_PartyName_FK] FOREIGN KEY([PartyNameId])REFERENCES [dbo].[Parties] ([PartyId])
It should probably be as follows.
ALTER TABLE [dbo].[PartyNames] WITH CHECK ADD CONSTRAINT [Party_PartyName_FK] FOREIGN KEY([PartyId])REFERENCES [dbo].[Parties] ([PartyId])
Note that I have swapped PartyNameId for PartyId.
