as the class has not a public constructor it cannot be serialized

Hi ppr,

sorry, I still don’t get what you mean. could you explain me more details?

because I didn’t change anything about DU Activities. just add more logic related to DB.

Perfect, issue solved together:

• checking all constraints on using persistence
• got luck to apply the strategy of deleting the unneeded variable
