I've been trying to get this sorted for the last two days and I'm having a lot of trouble with it. Basically, I am trying to create a Many-to-many relationship in the ProductTemplates module. The idea being that we want to create "bundle" products that contain multiple other products. I have the subpanels created and they do load links from the table. However, I have noticed that whenever a link is created, it creates two entries in the table, and the subpanels tend to load the same data, even when one of the entries in the table gets deleted.
I'm really not sure what else to try with this, so I am eagerly awaiting any advice anyone has.
