I cannot still explain my question above even when I converted the field variables to props (set/get).
Why it does not work in this particular case while other props I used for toggling an element’s color work in other components still eludes me. Plunker - Ionic 2 - Can't Hide/Show content in another tab, why not?
Nonetheless, setting the prop in my existing GlobalService.ts is working.
I feel I am making progress thinking the new way or at least how this framework wants me to do things.
You can confirm or deny it here
Thank you.
