Lift stack trace, no application frames

[Naftoli Gugenheim]

Hi, I found this in my inbox (application errors logged are emailed to me). It doesn't seem include enough information for me to figure out what triggered it. Any idea? (Is there any more information that such exceptions could include?)

Thanks!

Hi, I found this in my inbox (application errors logged are emailed to me). It doesn't seem include enough information for me to figure out what triggered it. Any idea? (Is there any more information that such exceptions could include?)

No.  It's the not joy of using combinators.

What version of Lift was this running against?

Okay... I couldn't track down the exact line, but someplace when you're doing:

"#foo" #> bar

The bar that you're passing is null and that's causing problems farther down the line.

I'm putting a few guards in to treat this case more gracefully

Thanks a ton.

Looking at the relevant snippets' source, it's probably MappedString#is that's returning null. Would changing 'is' to 'toString' fix it?

I don't think so.

[Naftoli Gugenheim]

Sorry for wasting your time when I should have looked into it more, but now I found this in MappedField:

override def toString : String =

  is match {

    case null => ""

    case v => v.toString

  }

So sounds like it would be a solution. :)

Thanks!
