Incorrect parameter types in invokeHttp

In Designer 8, when you try to import a remote XML file as data source, and create the corresponding view and table, the parameters of invokeHttp in the transformation created automatically are incorrect: 'stream' is assigned a blob datatype and 'result' a boolean one, they have to be manually switched for the transformation to work. Also, stream is not included on the default call, you either have to include it or use named parameters if you want to use the default value.
