[news.eclipse.modeling.gmt.amw] Re: Error while transforming AMW 2 ATL
|
Hi Marcos,
Thanks for your reply.
Yes, I get this error the moment I execute the HOT using the launch
configuration of Keys2NestedAMW2ATL.launch file.
I have not done any modification. To be more sure, I have deleted the
project and imported it again and I got the same error.
Is there anything I can do to find the cause of this error?
Thanks for your help,
Regards
