Guys,
What I have done is create a generic service that takes JSON data, and maps it to some html elements. Now when I map the enitre array of data to a field (I use encodeURIComponent and JSON.stringify it ) it's saved and worked. If I open and close make a change this mapping is lost.
I am too experiencing the same problem. any one knows what is happening?
I'll bet it's also related to my issue ...

... where JS in my map is lost if I cancel (not save) the map.
I'm able to recreate this issue when I have page that uses the template. When I apply changes to the template, the page that has the mapping loses it. I then have to recreate the mapping. It may be similar to your issue. Yes.
Now if you don't change that page again ... it seems to be ok, only when appery updates it or you make an update elsewhere on the page does it seem to lose it.
