#1 Methods equals of InteractionObjectPlus

[GOUAICH Abdelkader]

The method equals of the class InteractionObjectPlus
seems to be not working!!!
In fact I have the following log message:
...
[217] io = [(Ball, fromPONG) + (+pong representation)]
[218] io2 = [(Ball, fromPONG) + (+pong representation)]
[219] io.equals(io2) = false
...
