Problems with Session and transaction handling?
The problem I'm having is that the ProjectInclude is not persisting the ParmArr Collection. I've tried a few dozen odd variations, and I'm certain that there is something I'm doing wrong.
Ultimately I'm trying to avoid the back reference required for a one-to-many relationship.
Can anyone see anything obviously wrong?
The ProjectInclude table consists of a Single Identity, ID, the ProjectParameters table has a ParameterID Identity, Name varchar, Val varchar, dex int, and ProjectID int.
Of Possible Note: Manually inserting the relevant data into the database results in it being read in, the only problem seems to be the first insertion.
Any thoughts?
