Assigning anything to a Perspective property (session or component) turns anything not directly supported by JSON into a JSONified substitute. Completely breaking anything like byte arrays or other complex jython objects.

My free [Integration Toolkit module](https://forum.inductiveautomation.com/t/automation-professionals-integration-toolkit-module/74934/78) offers `sessionVarMap()`, `pageVarMap()` and `viewVarMap()` as an alternate storage location for jython objects that won't destroy their original form.

(There are alternatives using `system.util.getGlobals()`, but there be dragons.)
