Script for Automatic Smart Object Updates

Recently I wrote about how to make Photoshop auto-update linked smart objects when opening a file using actions and the Script Events Manager.

That method has one annoying drawback: Photoshop throws an error whenever you open a document without smart objects (because there is nothing to update).

So I wrote a small script that does the same update flow but safely handles files without smart objects. With this script, no error appears in that case.

1. Download updateAllLinkedSmartObjects.jsx and save it somewhere convenient, for example: `.../Adobe Photoshop CC 2014/Presets/Scripts/Event Scripts Only`.
2. Open Script Events Manager (`File -> Scripts -> Script Events Manager`).
3. Repeat the same setup as before (starting from step 6), but choose this script instead of an action.
