Hi folks
In the Language reference, it states that "the property can be implemented as a fact variable with the same name as the property".

I've tried this but I get an error
error c264 : No implementation for the property 'slot::aDiagram (i)' in the class 'slot'

Why doesn't it work?

I guess that you didn't declare the fact variable in the implementation:

Code: Select all

implement slot
...
class facts
    aDiagram : ...
...
end implement slot
