It's horrible !
My ruleflow have to execute 2 groups :
If i keep the "when" condition there is no action.
If i delete the "when" condition the action is execute.
Why my facts are not visible by the ruleflow !?
I don't understant, i hopte my probleme is simple to result because, my
ruleflow is simple and i have 2 rules...
Thx for your help
