How to define int array as retrun type for method in class diagram

[cahfofpai at tuta.io]

Dear Umbrello community,

is there a way to define an int array as return type for a method in a class diagram?

There is no array data type in the dropdown list for the operation type, and when I input "int[]", the type disappears from the diagram.

The Programming language is set to Java.

Your's sincerely
