[STORY | Chat] LPS-42584 As a Portal Administrator, I would like the ability to define which Social Relation types are allowed for Chat portlet

Hi Nate,

I'm sending this pull directly to you as you are the component lead of Chat portlet based on our Liferay Components Hierarchy sheet. :)

I tried to sum-up my proposed changes in the description of https://issues.liferay.com/browse/LPS-42584. This ticket was opened as a result of an Engineering thread. You can find the link in a comment at the LPS.

=== About my changes (in order of commits)
1 | LPS-42472 Autogenerated (missing) | 7417be0269f936ffafc17a2cc6000dd78f3880ac

I ran "ant build-service" for Chat before making any changes in order to separate the autogenerated stuffs. I've found that https://issues.liferay.com/browse/LPS-42472 was the last one in master that touched persistence_impl.ftl: liferay@c983514 and nobody has rebuilt the services for Chat since that commit.

2 | LPS-42584 Update custom query & StatusFinderImpl in Chat portlet to support multiple social relation types

The pattern comes from method 'getFindByUsersGroups_SQL'.

3 | LPS-42584 Add new property...

- You can see a pattern for including constants from a class in a properties file in the "portal.properties" for the property 'verify.frequency'. I didn't find a better way to list the available options.
- I'm not sure in the name of the new property
- I think, "social" sounds more general and expresses better the new functionality: social vs. site-based filtering
- Descriptions are always tricky :)

4 | LPS-42584 Add new service method 'getSocialStatuses': I've found better to create a new method and keep the original one for backward compatibility

5 | LPS-42584 Apply changes to DefaultBuddyFinderImpl:
- Is it necessary to keep the old conditions for "communities"? I don't think so, but I did not want to remove those without discussing it.

Please, review my changes & the LPS and let me know about your results.

Thanks,
Tibor
