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

Invalid parameter Name
Parameter name: paramName

   at Telerik.Microsoft.Practices.Unity.InterceptionExtension.ParameterCollection.get_Item(String parameterName)

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?

Kind regards,

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.

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:

[ParameterPermission("partner", PartnersConstants.Security.PermissionSetName, PartnersConstants.Security.Delete)]
        public abstract void DeletePartner(PartnerItem partner);

My "DeletePartner" method in my OpenAccessProvider then needed to have the attribute that is passed called "partner", whereas I had it defined as "product".

public override void DeletePartner(PartnerItem product)

public override void DeletePartner(PartnerItem partner)

Once I did a find/replace in my project, it worked. Hopefully this information will be helpful to someone.
