I can get the haystackInvokeAction to work with number,bool, and strings types, but not enums. Not sure if it is a syntax issue or a bug on the nhaystack side not handling it correctly.

**Request:**
haystackInvokeAction(@p:demo:r:29184cc3-47cb6fec, "C.Equips.Vav01.STATUS".parseRef, "override", {value: "OCCUPIED", duration: 10min})

**Response:**
haystack::CallErr: java.lang.ClassCastException: javax.baja.sys.BString cannot be cast to javax.baja.sys.BDynamicEnum
=== Remote Trace ===
