Description

This error message is generated when trying to add a variant product to a purchase order cart after features have been selected:
Error calling event: org.ofbiz.webapp.event.EventHandlerException: Problems processing event: java.lang.IllegalStateException: This object has been flagged as immutable (unchangeable), probably because it came from an Entity Engine cache.

To reproduce:
1. Add new feature "Gold" as COLOR Feature Type to Widget Features Category
2. Change WG-9943 virtual variant method to "Feature Tree Generation" on the product page
3. Add new "Gold" feature to WG-9943 on feature page of product app
4. Create new purchase order from BigSupplier for WG-9943
5. Select the new feature "Gold" as the color

The error is generated after trying to add the product after all features have been selected.
