When you serialize a list of items (for example, strings), only remain in final json first item (another items are missing).
Tested with last v8 master release.
in this source part of json loaded:
"EventUpdateTypes": [
"SelectionCurrentPrizeUp",
"SelectionLifeState",
"SelectionSuspensionType"
]
when you return to reset same items in "EventUpdateTypes", only appears first item like this:
"EventUpdateTypes": [
"SelectionCurrentPrizeUp"
]
After a quick view in code, error appear in :

when is iterating in each children, context variable never go to next child (remain in first child always)....
for fix, must to set:
....
context = context[currentKey];
if(child!=null)
jsonObj = child;
...
