Problems with CB stream in response to CB API loading

Hi Kyle,
I am having problems in implementing the new stream (great idea to have it though as it replaced stupid Jcomments). I have verified that the CB API is called (I am using the trigger “cbblogs-onBeforeUpdateBlog” for the moment as I cannot set the custom one). It indeed is in there (redirect upon trigger using auto action worked).
I have no idea what I am doing wrong. Debug does not show anything either ( testmunich.international-friends.net/events/ifm-activities/253-test-evet or see screenshot).
I have no conditions on it, have tried (just to be on the safe side) the [var1], [var2] as well as [var1_id], [var1_creator_name] etc…
See attached screenshots to see how I have set up auto action commenting stream (not any different than how it was set up).
Here is the trigger code that we are using:
Any idea what is going on?

That trigger is fired during the store process of a blog (when it's updated). You are then trying to display a stream during that processes instead of log activity. That isn't going to work as there is no display output as it's a store process. Joomla doesn't fire a CB trigger so you can not output a stream to comment on Joomla articles with CB Auto Actions due to this. CB Activity 4.0.0 will include a content plugin and provide functionality for comment streams on Joomla articles.

Which trigger do you want me to use then? Will a custom trigger do the job? Otherwise I can use onGalleryModal trigger and simply condition it.

There is no trigger available for that usage. Joomla does not fire a CB trigger so you can not add anything to Joomla articles from CB Auto Actions. onGalleryModal is not designed for such a usage either. CB Activity 4.0.0 will have built in commenting functionality for Joomla articles. The only alternative at this time would be to make a Joomla content plugin that fires a CB trigger or renders a stream directly.

I am not using a joomla article, I am using the event rendering of Event booking component. Should I use onGalleryModal trigger for that?

I have never talked about joomla article

Then you need to use a custom trigger implemented in your Event booking component.

Should I use onGalleryModal trigger for that?

No, onGalleryModal is not for that it's fired when a gallery modal is rendered.

I have never talked about joomla article

You mentioned JComments and it's used mostly for Joomla article comments so simply assumed; my apologizes.
