FlexSim 20.2.0, create a new model, add an object (e.g. Operator), double click, open Visuals Properties table.
There are three objects in the Properties Table (FlexsimModelFloor, Operator1, DefaultNavigator). Two exceptions are thrown probably because DefaultNavigator does have a visual attribute, but doesn't have visual properties:
exception: FlexScript exception: Property "value" accessed on invalid node. at MAIN:/project/exec/globals/properties/Shape>eventfunctions/getValue c: MAIN:/project/exec/globals/properties/Shape exception: FlexScript exception: Property "value" accessed on invalid node. at MAIN:/project/exec/globals/properties/Shape>eventfunctions/getValue c: MAIN:/project/exec/globals/properties/Shape
