Write a row to DB on UI load?

I would like to have an interface that, when it is accessed/loaded/refreshed by user, will write a row to a table in the database.

Is this possible?

 

Idea: Perhaps by using a!writeToDataStoreEntity, or a!startProcess? But it seems that these do not work outside of a "button click" by the user. Trying to add it outside of a button is giving me errors like this one:

Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error : Cannot create context for UI expression. Reason: A value of type "Reaction Tree" was stored in the variable "write", but values of this type cannot be stored in SAIL context variables. Use a with() variable or change the type of this value.

Thank you in advance for any ideas or advice!
