Rowy subcollection --> derivatives and listener.
Hey guys, I am struggling in rowy, trying to get data from a parent collection, in a subcollection table.
I want to show the data, without any listener. But I can not get it to show up until I add a listener, and change a value in that listener collumn.

Yes, derivative is the right thing to use here, could you please share any specific reason to not use listener. Adding docs for subtables - https://docs.rowy.io/field-types/sub-table. I haven't looked at the listners area, I'll take a look and will followup.
Ive never tried to use listener, will give it a try and let you know
I checked the link u sent, and it seems to be used for lists of data?
In my case I only want a string value, so i think derivative is better.
But my question was more: A derivative will never populate past data, right? Unless the listener is triggered.
Because in my case, the listeners are never gonna change. So the derivative wont trigger.
So are the only ways to populate a derivative column, by creating new documents, or changing the listener?
So Im just wondering, If I want to populate the column, if the documents were created before that column, how can I do it?
