Hi,

I'm wondering what is the best of doing the following.

Let's say we have the following grammar:

Entity:
attributes=[Attribute]* ('superClass'=[Entity]) ? ;

and based on the above rule we have the following:
index.php/fa/26087/0/

So, 'Lane' should also inherit 'shape' from 'MapObject'. In this case, when I use content assistant, I get MapObject.Shape , However, I need to get sth like Lane.Shape.

I mean the children classes should also have the parents' attributes when using content assistant.

How do you advise to approach this problem ?

Thanks,
Bests,
Parsa

Adapt scoping and collect all items

Hi Christian ,

Scoping is what I also thought about , but my concern is that if I add "Lane.Shape" in the content assistant, will it not throw error since Lane does not really have shape ?

Thanks,
Parsa

I don't get that point. Scoping DEFINES what is valid and content assist uses scoping
