Error deleting element

I have a custom module using OpenAccess and when I try to delete an entity I get the following error:

The entity does not inherit from content item. It's just a plain entity.

Hi Brian Crosby,

This is a very strange error, could you send us the code for your custom module so we could reproduce the problem locally?

What was the solution to this problem? I am getting the exact same issue, but, related to a class that does inherit from the content class. It seems to only occur when attempting to delete the master item, and I do not get the error when I try to delete a temp item.

I don't remember for sure what the fix was. But I think it might have been an attribute. Try removing any attributes you have on your method and see if that fixes your problem. Sorry I couldn't be more help.

Cheers,
Brian

I fixed this issue after hearing back from Support. Basically, I just had to do a find/replace on the word "product" for the word "partner" (in this case, I based my module on the product module and my module is for "Partners"). Support specifically pointed me to the ParameterPermission Attribute that I decorated my DeletePartner method with, which I had defined as so:
