Hi Guys!
I would like to know what types of providers/managers/events I should to implement within my "custom" jive object type to get possibility follow him in my custom activity streams. Any constructive help would be appreciated. 
Thanks in advance, Dzmitry.
Ryan King Do you have any ideas/suggestion on my question ?
Hi Dzmitry,
You get the ability to follow a custom content type for free, in that your custom content object needs to extend JiveObject. All that really is required is making sure that the Follow option is available on the screen, using the @jive.socialActions macro in your content's sidebar.ftl, and in your EAE soy templates.
Note that in order for your content to be exposed in the EAE activity streams at all, you need your type to implement RecentActivityEnabledType.
