BUG: Active Template Library Implement Connection Point Wizard Generates Incorrect Code (315149)

MORE INFORMATION

Steps to Reproduce the Behavior

1. Use the Implement Connection Point wizard to create a default ATL project, and then click Finish.
2. Add an ATL simple object with support for connection points:
   1. In Solution Explorer, right-click the project name, and then click Add Class.
   2. In the Add Class dialog box, click to expand the node under Categories, and then click ATL.
   3. In the right pane, under Templates, click ATL Simple Object.
   4. Type a name (for example, Test) in the Short name box.
   5. In the left pane, click Options, select the Connection points check box, and then click Finish.
3. In Solution Explorer, switch to the Class View, right-click the objects class CTest, and then click Add Connection Point.
4. Select the project's dispinterface, _ITestEvents (for which a connection point is already present), click the > box, and then click Finish.
5. Open the header file, Test.h, for the object that you added earlier, and note that the wizard has generated an additional line of code as follows:

   __event __interface _ITestEvents;
   					

6. Build the project; you receive the following errors:
   Test.h(66) : warning C4921: 'source': attribute value '_ITestEvents' should not be multiply specified
   Test.h(66) : error C2500: 'CTest' :

   'ATL::IConnectionPointImpl<T,piid,CDV>' is already a direct base class
           with
           [
               T=CTest,
               piid=& _GUID_ed85b6e7_9f61_40f0_9ce0_46cd76428282,
               CDV=ATL::CComDynamicUnkArray
           ]
   						

7. To resolve the error, remove the line of code that is described in step 5.
8. Build the project again; you receive no errors.
