I focused mainly on the WebIDL things. At first, i performed an online check [1] to be sure that our code is syntactically correct. I investigated further in the comment about handleEvent and Callback functions. In section 3.2 of the current WebIDL spec [2] a "warning"-note says the following: > > Warning: > Specification authors should not define callback interfaces that have only a single operation, unless required to describe the requirements of existing APIs. Instead, a callback function should used. > > The definition of EventListener as a callback interface is an example of an existing API that needs to allow user objects with a given property (in this case “handleEvent”) to be considered to implement the interface. For new APIs, and those for which there are no compatibility concerns, using a callback function will allow only a Function object (in the ECMAScript language binding). > > This is exactly the case for the three interfaces "PropertyCallback", "MetadataCallback" and "ErrorCallback". Our interfaces do not need further (optional) inputs that would require a callback interface in the sense of WebIDL. Further, an EventHandler or -Listener is not needed in this place. The examples in the section 3.2 [3] justify this. Maybe the abstract naming of the methods in handleEvent led to misinterpretations and caused the correlation with events. > > Cheers. > > [1] http://www.w3.org/2009/07/webidl-check > [2] http://www.w3.org/TR/WebIDL/ > [3] http://www.w3.org/TR/WebIDL/#idl-interfaces > _____________________________ > Dipl.
