[SOLVED] Variant-Methods not available on ObjDef

Hi

I defenitly have an ObjDef "in hand". But all tries to get any variant-info about this object returns in error.

I tried oObj.isVariant(), oObj.hasVariant() as well as oObj.Master().Name(nLocale)

I allways get a TypeError: Cannot find function isVariant in object ObjDef ID=....

I do similar things with models. All Methods above works as designed. Why can't I access the methods for Objects?

It's ARIS 7.2.0

Thanks for any ideas
