I've created an ECT w/ Read List and Read Item operations using SharePoint Designer, saved it, and given myself permissions. The ECT's external data source is a WCF service.
When I try to create an External List using the browser, the ECT does not appear in the External Content Type Picker.
When I try to create an External List from the ECT in SharePoint Designer, I'm shown the following error:
Could not save changes. No Finders available in the View Group associated with the SpecificFinder (Read Item) operation 'FindWidget' on Entity (External Content Type) with Namespace = 'http://widgetserver', Name = 'Widgets'. The list cannot be created.
How can I create an External List based on my ECT?
