Perhaps you can create a private function whose arguments is the
structure's keys,
For example:
public function foo(required struct myStructVar) {
// sanitize myStructVar into a correct struct with all default value
var myPopulatedVar = func_populate(argumentCollection=myStructVar);
// do something else
}
private function func_populate(string var1="", numeric var2=0, string
var3="ABC") {
return arguments; // return everything that was passed in, plus the
default value if not exists
}
