Tree Navigation link command

[giampiero]

Goodmorning everyone.
I have a problem with the navigation tree.
I created 2 new metaclasses (A and B) and their Metaassociationend.
So I created a new tree for the new metaclass A, to which I attached the Standard Navigation.
The new tree shows the folder and the objects of the new class A.
The problem is that clicking the right button on the folder appear (and it work) create a new object, but clicking on the object does not appear the link command to connects to the class B.
Where am I doing wrong?

Hi giampiero,

On the metaclass, UserInterface / MenuCommand on your A.LinkChildMenuCommand with the default macro LinkChildmenuCommands add your legs (to B).

As a result in the navigation tree, sub menu "Connect" your legs will appear.

I think it was your question.
