As the "Object type" property is a state list, it can't be used to filter an object list.
Static objects often need to be distinguished from dynamic objects, so there needs to either be two new functions to do this, ie.
Location.Objects.Dynamic
Or a parameter added to Object lists/groups, ie.
Location.Objects(Dynamic)
Completed in release 5.0.31
The syntax used is to have the key of the state property with the state value in parentheses after it:
%location%.Objects.StaticOrDynamic(Dynamic)
