Mock method return with one of parameters

Im tryng to mock the return value with one of parameters, in this way:

    when( myService.saveMyEntity( TENANT_ID, DEFAULT_USER, Mockito.any( MyEntity.class ) ) ).thenAnswer(
            new Answer<MyEntity>() {
                @Override
                public MyEntity answer(InvocationOnMock invocation) throws Throwable {
                    Object[] args = invocation.getArguments();
                    return (MyEntity) args[2];
                }
            } );

But I got the follow error:

org.mockito.exceptions.misusing.InvalidUseOfMatchersException: Invalid use of argument matchers! 3 matchers expected, 1 recorded:

Whats the problem? How is the correct? Im using mockito 1.9.5 Thanks in advance for any help.

You've to either use matchers for all the arguments of saveMyEntity method, or for none. You've to change that to:

when(myService.saveMyEntity(eq(TENANT_ID), any(User.class), any(MyEntity.class))).thenAnswer(
        new Answer<MyEntity>() {
            @Override
            public MyEntity answer(InvocationOnMock invocation) throws Throwable {
                Object[] args = invocation.getArguments();
                return (MyEntity) args[2];
            }
        } );

Also, as noted from @JBNizet's comment, since you're returning the last argument from your answer, you can use AdditionalAnswers.returnsLastArg() factory method:

when(myService.saveMyEntity(eq(TENANT_ID), any(User.class), any(MyEntity.class))).thenAnswer(AdditionalAnswers.returnsLastArg());
