[henshin-user] Strange "Error parsing JavaScript expression" validation

[Jens Bürger <buerger@xxxxxxxxxxxxxx>]

Hello everyone,

in the attached transformation module I get validation errors in the 
"Problems" window of Eclipse when using rule parameters:
sun.org.mozilla.javascript.internal.EvaluatorException: missing formal 
parameter (<Unknown source>#1) in <Unknown source> at line number 1 in 
<Unknown source> at line number 1

Moreover, I sometimes get an error dialog when closing the Henshin 
diagram window:

"An internal error occurred during: "Henshin Validation".
java.lang.NullPointerException"

This problem also exists when using the git master branch of Henshin.

Kind regards,
Jens
