It is possible to update Cache object property from Python using the following Python code, with import of intersys.pythonbind3: my\_object.set("my\_property",["A","B","C"]) However, I am unable to save 2D %List with 2D Python array like the following: my\_object.set("my\_property",[["A","B","C"],["1","2","3"]]) I am not sure whether this is Python-Cache bind flaw or design issue. Is there any alternative/ workaround to do the same for above?
