Attribute.isAssociation in metamodel API returns false for relationship mappings [message #548476]

Hi there,

I found in the eclipselink metamodel API, the method Attribute.isAssociation always returns false for those attributes of relationship mappings. For example, in an Employee and Department example, the entity type Employee has an attribute named "department" which is defined to be a many-to-one mapping. The method Attribute.isAssociation for the department attribute returns false.

So I wonder what exactly "association" means here in the metamodel API. I thought it means relationship mapping.

Thanks for any help

BTW: I'm working with EclipseLink 2.0.2

This is a bug in our meta-model, it should return true for 1-1, m-1.

Please log a bug for this.

The issue is our code is internally calling isReferenceMapping() but should be calling isObjectReferenceMapping().
