W102 Enumeration Causes Method Parameter Ambiguity
Umple semantic warning reported when an enumeration makes a method parameter's type ambiguous. This occurs when there is another class that could also be the parameter's type.
Example
// This example generates the warning
// because it is ambiguous if "param"
// is an object of class "Y" or
// the enumeration "Y".
class X {
enum Y { Red, Blue, Green }
showY(Y param) {
System.out.println(param); }
}
class Y { }

Solution to The Above So the Message No Longer Appears

class X {
enum Y { Red, Blue, Green }
showY(Y param) {
System.out.println(param); }
}
class Z { }
