I had this "problem" too, but Mike said it should work, and from memory it worked for a test case I did, but it didn't work in a specific project and the problem seemed to be because of non-model attributes that I had in this entity. Sadly, I didn't find the source of the problem before I left my job. > What I want to do is create an Action method that allows me to look for an > existing intervening object based on an attribute, and if one doesn't exist, > then create one.
