Hi all
When i generate and use diagram i always get error from diagram but don't understand.
i have 4 ecore meta-model and i need to generate 4 diagram. But cause of bidirectional model referance i need the use 1 edit and 1 model project (couse of cycling plug-in error from java) so i configure my genmodels to do this. And i can generate one model plug-in and 1 edit plug-in
But when i follow this steps i always get this error;
Anyone can help me ?
Regards.
