The current code prevents executing a rule if one of the facts listed in the parameters of the condition or the action is missing. It would be nice to be able to modify this behavior so that in some situations missing facts do not prevent the execution of the rule if they are specified as being optional (issue #390).
In this PR I take into account the
@Nullableannotation on parameters to consider them as optional.I know that easy-rules is in maintenance mode, so I'm not sure this PR will be reviewed and merger on master... Can you tell me if it's possible or if I should use a forked release for my needs ? Thanks in advance.
