Re: [henshin-dev] MetaModelEvolution & Update

Hi Amalia,
Quoting NA S <anoniems@xxxxxxxx>:

Yes, I got an exception, because MM_CreateRefClass is not applied.
Exception in thread "main" java.lang.NullPointerException

I tried reproducing your problem and would suggest you try to copy the
files from the "backup" folder into the "model" folder before running
the example. I could not reproduce your problem with the original
contents of the "model" folder, but after I ran the program and the
model folder's contents were replaced during the transformation and
then tried running the program again, I got exactly your error, so I'd
try if replacing the contents works.
