Default null for dynamic virtual interface array in the method parameter list

In reply to dave_59:

Dave,

So based on your explanation why isn’t the following syntax working? Obviously, you just cannot directly assign null to array type of virtual interface variable, right? How should I do it then, only option is as rohitk stated?

..., virtual interface test_if ifs[] = null);

Again, thanks already in advance for your reply!
