9 years ago No solution yet, but a few findings:
- It appears that all data is successfully retrieved from the API, however the zoom level ends up being incorrect (possibly a default value).
- The issue has been observed on Chrome now also, (in private browsing mode for no cache, with dev tools closed).
- With the embedded frames pointing at ox-it.github.io/embed.html, the issue also cannot be reproduced.
I suspect this may a fairly sensitive timing issue where some other system is causing a change/reset of the map's zoom level, which sometimes occurs after the POICollection has set it to the desired value. UpdateBounds() does get called twice via MapView.resetMapContents(): once when the POIcollection is first assigned to the map view, and then a second on sync of the collection.
Under some circumstances, an embedded view will show at a default zoom level framing Western Europe. Map content is present upon manually zooming into oxford.
This is fairly easily reproduced when viewing the embedding instructions via github.io: http://ox-it.github.io/maps.ox/embedding.html
On my system, using Safari 7.1 panels containing a #?custom path will exhibit this problem on around 25% of refreshes. I've not been able to reproduce it in Chrome or Firefox, nor in Safari while the Dev tools panel is open. It doesn't seem to happen on Martin's Macbook.
When one of the embedded custom map fails in this way, all custom maps embedded in the same page do so.
I've seen this once happening to a search view.
