With CB Auto Actions 7.0.0 you can now act on Joomla events. So yes this is possible now. Prefix Joomla events with "joomla_" when supplying your triggers. See the below for Joomla content events.

docs.joomla.org/Plugin/Events/Content

In your case for example you'd supply a trigger of joomla_onContentAfterSave, which has content, article, and isNew variables. You can access the article object with [var2] so for example [var2_catid] would be the category id. Joomla events tend to be wide reaching though so you probably will want to condition the content variable to make sure it's an actual article. The below condition would probably work.

[var1] Equal To com_content.article

Is there any reason possibly that conditions are mandatory for some of these triggers?

You need to condition the context because Joomla content triggers are not limited to Joomla articles. They're used in a lot of other locations. Enable debug mode and maximum error reporting in Joomla global configuration then in your auto action enable Debug under the Parameters tab to output an errors so you can see why the auto action is failing. Beyond that I can not advise you on using Joomla events and you'll need to refer to Joomla documentation regarding them.

See my above reply regarding debugging an auto action. It's probably failing on your [article_id] substitution, because that substitution doesn't exist. Same applies to [context]. You can't access trigger variables by their variable names as CB Auto Actions has no way of knowing these. You have to access them using var1-15 (e.g. [var1_id]). For example if using joomla_onContentAfterSave then its variables are as follows.


With the above you'd change [article_id] to [var2_id] and [context] to [var1].
