oxid-esales / extend-user-demo-module Goto Github PK

and can you give me a hint for getting started with this module?
I'm getting this Error after activation:

MODULE-ID | PROBLEMATISCHE DATEIEN
-- | --
extenduser | OxidEsales\Eshop\Application\Model\User\UserUpdatableFields => OxidEsales\ExtendUser\UserUpdatableFields

Since this module is marked as deprecated, I am not sure if it should still work with OXID 6.2.2., but if so, I am having the following problem:

After intsalling and activating the module, if a new user registers, the new field "Additional contact info" is displayed during the registration process. However, nothing (for this field) is saved in the database table oxuser.

On the other hand, if an existing user updates the billing address, the entered value is stored in the table.

Is this expected behavior? If not, could it be a result from using OXID 6.2.2 and the module being deprecated?

Is there any easy way to extend a model in OXID 6.2.2?
