           Summary: Custom bindings for Cliipboard::types() shouldn't
                    return null if empty
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dcheng at chromium.org

The spec does not define DataTransfer.types as a nullable type:
15:06 < dcheng> Question... if the spec defines an attribute to return a DOMString[], it would be 
                incorrect to return null if it's empty right?
15:07 < annevk> dcheng: yes

So we shouldn't ever be returning null.

Mozilla's implementation of DataTransfer confirms this: http://mxr.mozilla.org/mozilla-central/source/content/events/src/nsDOMDataTransfer.cpp#265 always returns a non-null list (unless the allocator failed).
