Integration of Joomla com_content categories in activity streams

HI,
one part of my project is CB, the other JReviews. JReviews includes plugins to integrate new listings and reviews in CB streams. I tried to create an asset for an JReviews activity stream, e.g. "Recipes". It doesn´t wor. If somebody publishes e.g. a new recipe there is no entry in the recipes stream nor in the recent or profile activity stream.
JReviews uses com_content for its listings. Is there maybe another way to integrate this content in an asset of an activity stream? Maybe with the category ID of Joomla content?
Best regards Uwe

Not sure what you mean by integrating com_content categories? Joomla article activity support is built in and only needs to be toggled on in CB Activity > Parameters > Activity > Article. This will create activity with an asset of "article.ARTICLE_ID".

We've no JReviews integration in CB Activity, but am not sure what there's to integrate beyond the original article itself. I'm not sure what their plugin is supposed to be doing, but is maybe for an older release of CB Activity? Adding custom activity to CB Activity can be done relatively easily entirely using template files. See the below for examples as there are examples included to help get you started.

Asset parsing can also be entirely extended from template files. Examples for this are also included as follows.

Access Checks:
/components/com_comprofiler/plugin/user/plug_cbactivity/templates/default/assets/access/example.php
Context URLs:
/components/com_comprofiler/plugin/user/plug_cbactivity/templates/default/assets/context/example.php
Dynamic Grouping:
/components/com_comprofiler/plugin/user/plug_cbactivity/templates/default/assets/group/example.php
Source Parsing:
/components/com_comprofiler/plugin/user/plug_cbactivity/templates/default/assets/source/example.php

Notifications can also be extended from template files. The below example is also included.
