Polymorphic type checking?

[WD0001]

In VB.Net, you can use an expression like "TypeOf obj Is Node", which will return True if obj is a Node, or if it is a type that inherits from Node.

How can I use a Simio expression to do something similar, to return True if an object is either a Server, or is subclassed from a Server (or a subclass of a subclass of a Server, etc)?
Simio's "Is" keyword doesn't respect polymorphism.

Hi,

it worked just fine with a subclassed server here:

Using a object reference state variable named "Test" on the ModelEntity: (Assign step was just ModelEntity.Test  ->  Server)

Ok, it is working now. I'm not sure what I changed to fix it, though.
