Trying to notify different Collections from same Publication via Observe and DDP messages

help
1

Hi there,

Maybe I’m approaching things the wrong way but I’m trying to notify different Collections of changes from the same Publication,

I have a Selections Collection and a Projects Collection

I have a Publication that I Subscribe to at some point

and all works fine as long as I stick to publishing to one Collection

I’m using Cursor.observe in the publication and wanted to do something like this (I removed added and removed callbacks for clarity) :

const selections = Selections.find();
const _o = selections.observe({

            changed: (selection) => {

                if (selection.project_id) {

                    this.changed('Projects', selection.project_id, { modifiedAt: new Date() });

                }

                this.changed('Selections', selection._id, transform(selection));

            },
            
        });
```

I'm using the websocket panel in devTools to watch what's happening and the 'changed' ddp messages are only sent to the _Selections_ Collection

As I read the docs and the "counts-by-room" example in the `publish` chapter I was under the impression that you could dispatch to any Collection of your choosing

I also tried only publishing to _Projects_ but this does not work either

finally it seems like using `added()` works as expected but I'm not being able to use `changed()`

probably missing something obvious but I thought I'd ask and see if some one can help me in the right direction

thank you
