Fixed: Down the log level to inform when a property number is empty When you call a property number undefined, UtilProperty return the default value and you have in console a warning : UtilProperties |W| Error converting String to Integer; using defaultNumber 60. Or in general if you call and resolve an empty value for a property, they is no reason to inform it as error.
