Problem with associations and attributes

Dear all,

I attach an example where I have a class A and a class B. The class A has an attribute that is a reference to the class B with the corresponding association. When I delete the attribute or the association both are deleted. This was done with a previous version of Visual paradigm. I created the attribute and then I could select “Show association” and the association appeared.

Now with the new version 10.2 I can’t find how to create this same example. Could some one help me? This is really useful to avoid that you delete the attribute but you forgot to delete the association.

Thanks
