[Gambas-user] difference ME and SUPER with inherit

[Mayost Sharon]

Hello
 
Yes I am this Gambas-user
To learn from you

But when I try to run the sample it gives an error
(I am attaching the sample file "super2.tar.xz" again) for me it gives an error
Can you fix the error for me?
And so I can study well

You helped me a lot when you wrote "recursion loop"
If I understood correctly, in the "Clear" part of the example it doesn't matter if we use ME or SUPER
' Reimplements the Clear method
public Sub Clear()
Super.Clear
$aKey.Clear
$cValue.Clear
End

Many thanks again to all the helpers
