I've got a multitenant BCS service setup. It all seems to work; I've imported my model and it properly lists the entities in the model. But when I try to create an external list based on the model, the picker doesn't list any entities. Upon opening the picker, I notice the following lines in my ULS logs:
ValidateEntitySecurity failed for entity: Customer
Ok, so apparantly there's a security issue. But I've checked the permissions in the BCS config, even granted full rights to everyone just to be sure. So on all the places I know I can configure things, I did. But still there's a security error and now I'm not sure why any more.
