This problem has stumped me for some time. Maybe @OliverRodrigues @Fubar or @ragavanrajan can figure this one out.
I'm trying to build a clickable tabbed navigation per @ulrikke 's article here. I have everything setup correctly and have checked and double checked all of my code, localized page records, web template code and etc..
You can see my page renders correctly in the studio along with my blue tabs. Please ignore the bad styling for now. You can see I've also added console.log statements to debug the liquid code and all the returned values are as expected.

Now, once in Preview, the child/parent association breaks for some reason. Notice the blank values in my console.log statements for children size and child pages list as compared to the previous screenshot

Finally, below is Ulrikke's liquid web template code followed by what is actually rendered in my browser. Notice how my Nav is not populating.


Does anyone have other troubleshooting ideas? Could this be a bug? I am using a GCC environment btw. I've also tried clearing my cache & config multiple times and even restarted the portal to no avail. Any help would be apprecaited!
