Comment 5 Alexandr Scherbatiy 2009-11-18 06:30:54 UTC 
Steps to reproduce:

- Copy the code to the editor:
-----------------------------------------------
class A{}
var seqf = function(a:A[[ | ]], b:String[[ | ]]):Boolean[[ | ]] { [] };
-----------------------------------------------

The exception pops up.
Comment 6 Karol Harezlak 2009-11-20 08:03:50 UTC 
Not much I can do except hide this exception. For some reason tree node is in inconsistent state and calling node.toString() cause NPE. I think it's not a stopper so I'd rather fix this issue in incoming patch then in this release but decision is up to QA.
Comment 7 Karol Harezlak 2009-11-20 08:07:29 UTC 
It looks like it is on the list of issues to fix so I'll fix it asap.
Comment 8 Karol Harezlak 2009-11-20 08:24:02 UTC 
fixed,
