But a Java primitive does not. That's where it gets confusing. AS has only one Number type, not two like Java. Since a primitive CANNOT be null, you have to stick with the least common denominator ya know?
CORBA had this too, hence the structure solution. Unless AS has both a primitive and an Object numeric type I dont know how else to do the data type mapping but to stick with a 0? -- Dave Wolf Cynergy Systems, Inc.
