[TYPO3-mvc] How to add a unique/primary key property to a manually created domain model?

[Henjo Hoeksma | Stylence]

Hi Jan,

you are updating the basket in your session, which is not the same as in
persistence. Make a choice to either save it to the session - or to the
persistence layer.
Since your basket is not run through the persistence layer in your code, it
is not persisted there. You are trying to mix both approaches here.
Stick with one of the two.

Summarising: Updating your basket in session is not the same as in
persistence.

Kind regards,

Henjo

Problems are small because we learned how to deal with them.
Problems are big because we need to learn how to deal with them.
