[rules-users] Creating HashMap object in rules

[Esteban Aliverti]

According to java documentation the result of Map.put is:

"the previous value associated with key, or null if there was no mapping
for key. (A null return can also indicate that the map previously
associated null with key, if the implementation supports null values.)"

Are you sure that you are doing what you think you are doing when you do:
$testObj.getResult().add($rule.put(.....)) ?
