SHORT DESCRIPTION

Assign a default value for an optional argument of type object so that changes made in definition rules remain in the object

DESCRIPTION

Version 0.4.0 introduces the concept of rules that extend the functionalities of the library.
Definition rules are always executed because they are executed during the argument definition.
However, for arguments of object type the value is null when the argument is not mandatory , and this can create some issues with rules that use this object.
Actually, if you try to set a value for a property that is an object in the data maodel, the library treat this property as a mandatory paramter.

It is needed to set a default value for an object even if the parameter is not mandatory
