    Default Issue with multi input mapping sub transformation

    Hi, I'm writing a sub transformation to accept two streams through mapping input. I have tested the sub as standalone and it works fine. But I call it from an external transformation, it doesn't show any data in preview (step metrics show some data coming out).I have faced this no preview issue before as well. Any ideas? Please see the attachments.
