@ulrik Ok, I solved it with
Engine.loadFromJSON()and
Engine.dumpAsJSON()I collected all Panel.getValue()'s and stored them as objects and could get them back after a new start of the app.
So instead of manually script all getValues and setValues, would it be possible to collect all components values in one go, like you can with
Content.storeAllControlsAsPresetand then save it with Engine.dump...?
