While trying to insert parent child composite key linked into a database I received this error:
- Ungültiger Index N für SqlParameterCollection mit Count=8
- Invalid Index N For This SqlParameterCollection with count=8
When I added the:
attribute to the 8th property in my mapping file, the issue was resolved. Start with the ID at 0 and then count down the file.
The problem was that in line 1 I had the same column name identified as I had in line 8. I needed the value in both places because line 1 was a property and line 8 was the:
relationship. Adding the:
attribute to the to the:
resulted in being able to save the parent child relationship.
