                                .doOnNext {

<@UBLEQB51A> This is... interesting and it might be possible that your implementation idea is not quite right.  In an ideal world, your dataset should be an observable list.  The set itself is a set of models which should have properties themselves.  In debugging mode, you could check to see if there is a dirty state to track in your tag bars. To be fair, I haven't looked super hard into tag bars so I'm not sure if there's a streamlined way to implement this as easily like it would be for tables or whatever

I'm pretty sure it's not right, but it is working heh. 

go ahead and post your models and the implementation of the tagbar itself let's take a look

I only saw the `dataModel.tags.onChangedObservable` part is that what you're talking about?

I didn't do an observable list of properties, because the property itself is just a list of strings, or at least that's how I'm thinking about it. And its possible I'm doing it all entirely wrong heh.
