I'm trying to use the variable definition syntax editor ferature to define and use a common list of members.
For example, i try to define a @foo variable, contains three member as in the picture below:

then I define a class "foo", put the variable @foo in the member list and adding a member named "top" (figure as class icon), as show in the picture below:

finally, I define a class "top" and put the variable @foo in the member list, like in the picture below:

When I try to obtain the popup autocompletion list for the the foo class I could see only the top element (I expeted to see the "element1", "element2" and "element3" members too!).

And when I try to obtain the popup autocompletion list for the foo.top class, I see no autocompletion popup.

Where is my mistake?
Thankyou in advance.
Waiting for your reply.
Best regards
