Bugs

I upgraded my store from 4.1 to 4.3, then added the Emporium theme which was an upgrade from Traction 4.1.

The SS_JC_JCarousel table did not have the ID column as a primary key, and it was not set with IsIdentity. So when I went to add a new JCarousel to my site, an error occured:

SqlException: Cannot insert the value NULL into column 'Id', table 'mydb.dbo.SS_JC_JCarousel'; column does not allow nulls. INSERT fails.

I was able to fix the problem by setting the ID column to primary key and IsIdentity.

I'm not sure where in your scripts this issue would need to be fixed. Figured I'd report it for anyone else experiencing the same issue.

Please do not modify the constructor but resolve any dependencies directly or use Property injection instead as described here.
