I was trying to extend the Portfolio metaclass in MEGA to add a * collection of associated Application objects.
On the MetaOppositeAssociationEnds folder within the Portfolio metaobject, I tried to invoke "New->MetaAssociationEnd", however after asking for the association Name in the "Creation of MetaAssociationEnd" dialog box, an error message was given stating "Unable to generate command for MetaClass MetaAssociationEnd".
I was wondering if anyone has come across this issue and have they been able to find out what is the underlying cause?
Solved! Go to Solution.
If you want to create a MetaAssociation between two MetaClass, use the 'Metamodel diagram'.
A metamodel diagram described an object of the MetaClass 'Metamodel'.
In this diagram, you can create a MetaAssociation with a drag and drop action between two MetaClass.
A window opens where you juste need to name the new MetaAssociation.
Then the MetaAssociation is created with its MetaAssociationEnds.
After this, you can change default properties for MetaAssociationEnds (Local Name, MetaMultiplicity...)
HOPEX Studio - MEGA Studio, section 'Placing a MetaAssociation'
You need the MetaStudio product to customize metamodel.
That worked very well! I appreciate the quick turnaround!
