Glad you solved the problem! In my personal experience it’s always best to compile and look at errors directly in sbt when “things go weird”. IDEs sometimes get confused in their own ways, slightly differently than the actual scalac compiler, when you do much type-level things.
Happy hakking! -- Cheers, Konrad 'ktoso’ Malawski Akka @ Typesafe On 30 March 2015 at 01:32:46, Allen Nie ([email protected]) wrote: Dear Konrad, Thank you for responding. I solved the problem. It turns out my original type was very wrong: type RowIterator = Either[Iterator[OrdinalRow], Iterator[NamedRow]] I changed it to type RowIterator = Iterator[Either[OrdinalRow, NamedRow]], and it works fine now! The perplexing error message was produced by IntelliJ's in-line warning, and when I compiled, that warning never appeared. The compiler gave me much nicer warning and I found the bug.

The error looks a bit weird… We don’t have any parameter named g2 (well, it only takes one parameter) in the snippet you provided. Would you be able to provide a more complete snippet and complete compile error?

Then I wanted to start constructing a source: protected val source: Source[NormalRow, Unit] = Source(() => data.dataIterator) data.dataIterator returns a iterator with RowIterator type. However, it says "unspecified value parameter g2"....Can anyone let me know what's going on? Why is this happening and can it be fixed?
