Serge Huber commented on UNOMI-132:
-----------------------------------
Hello Donnie,
So if I understand correctly your problem is that it overwrites (but still
keeps a nested structure). If you want to really "merge" nested properties I
think a new type of property merge executor should be implemented, because this
is a specific operation that might not be desired as a "default" strategy.
Regards,

> ProfileServiceImpl mergeProfiles for nested profile properties

> Key: UNOMI-132
> URL: https://issues.apache.org/jira/browse/UNOMI-132
> Project: Apache Unomi
> Issue Type: Wish
> Reporter: Don Hinshaw
> Priority: Minor
>
> When merging profiles unomi does not look for profile properties that are
> nested.
> {code:javascript}
> "properties": {
> "nbOfVisits": 1,
> "lastVisit": "2017-10-25T20:04:49Z",
> "group": {
> "user_ids": {
> "site_1": "123_user_id"
> }
> },
> "firstVisit": "2017-10-25T20:04:49Z",
> }
> {code}
> When this profile gets merged, unomi looks for the properties on line 458 in
> ProfileServiceImpl.
> {code:java}
> allProfileProperties.addAll(profile.getProperties().keySet());
> {code}
> The keySet() will only include "group", not the values nested inside. So we
> cannot define a mergeRule for the values inside.
> How can we merge two profiles with different user_id values?
> Current work around is to use
> {code:javascript} group_user-id_site-1 : "123_user_id" {code}
> instead of the nested property.
> Any thoughts or is this a new use case?
> Thanks,
> Donnie
