I created my metamodel in KM3, and then transformed it to MOF-1.4 with no

Hi,

It seems that the target element was not created for some reason (e.g.,
abstract class, non-existent). But this should have been reported before
the error you mention.

Are you sure there is no other reported error before the
IllegalArgumentException?


Regards,

Frédéric Jouault

Hi Frédéric,

when I closed Eclipse, and run it again it works now. It seems to me that
problem was some custom datatypes which MOF-1.4 doesn't support.

Best regards, Milan Milanovic

I'm experiencing a similar exception like reported in this thread.
For some reason, the rule 'copy_VLIW' lets the engine crash :

rule copy_VLIW {
from m : meta!VLIW
to m1 : meta1!VLIW(
averageClaim <- m.averageClaim,
minClaim <- m.minClaim,
maxClaim <- m.maxClaim
)
}

This is just a copier. I'm using ATL 2.0.0RC4, EMF 2.4.0, Eclipse 3.4.0.
ATL is invoked programmatically here.

I've checked the meta-model, the element in question (VLIW) is non-abstract.

Yes.

How can I get this working?
