I am having a bit of a difficulty with Wonder D2W project that I am using to test out an MS SQL Server model for a class and I am hoping to work out the details of our favorite technology, soon. The error occurs when trying to populate a table in the database, in this case the "dept" table. I have produced a record of my work at http://venus.cs.ttu.edu/groups/webobjects/wiki/f136d/Reverse_Engineering_a_MS_SQL_Server_Database_with_Entity_Modeler.html, which is intended to be completed as class example for a database course (preferably using WO.) I could definately use some assistance from the gurus on this one.

In a nutshell, this is intended to be as "plain vanilla" of a D2W example as possible given that we are using a MS SQL Server 2005 database. The good news is that D2W/ Entity Modeler were/ are good for debugging such the database model. The down side, the error shown below is generated when trying to save a new entry in to the database such as dept= {dnum = ?, dname = "pain", mname ="", length= "0", takess = null} where dnum is the key and is a nchar of length 10.

I suppose the question is, how do I ensure that D2W or the database generates a key when it otherwise does not display it? Or should it come from the database, and if so how do I set that property?
