Ho can i get rid of the `"` when i do a `.addAll`

```
  var obs = Observable(0);
  debug_log("Numbets to add: "+listUserIdForLifeFeed.value.toString())
  obs.addAll( listUserIdForLifeFeed.value.toString() )
  var obsArray = obs.toArray(); 
  debug_log("the new numbers: " + JSON.stringify(obsArray))

```

debug log:

```
	LOG: Numbets to add: 33,34,211,37,36
	LOG: the new numbers: [0,"33,34,211,37,36"]
```

Hi Kevin,

you are adding a _string_ to the other Observable. If you want to add all of the numbers from the source Observable, you should instead try this:

```auto
obs.addAll( listUserIdForLifeFeed.toArray() )

```

that give me:

Oh, sorry, my bad. `.toArray()` is a member function of the Observable, not its value. I have edited my post above to show the correct code.

It’s this: `obs.addAll( listUserIdForLifeFeed.toArray() )`

That will of course only work if your `listUserIdForLifeFeed` is an Observable list. If it is a single-value Observable that holds a string, you will need a different approach that splits the string into an array first.
