Device in question is edge 540 solar, latest beta firmware and few older betas, and also last stable version (I switched to beta thinking maybe this will work in new firmware).
I have datafield with "out of memory error" in simulator and device so I implemented (:extendedCode) annotation to a few places. In simulator runs fine but when uploaded to the store as beta and added to device as soon as I try to add datafield to activity it blocks/halts entire device to the point of unresponsibility. It hangs there for 15 seconds or so, says "collecting diagnostics" and reboots.
On feinix 7 it works fine with same extendedcode annotations but that device has more memory so extendedcode isn't even necessary.
What happens with edge though? I've never had some datafield completely crash device.
Has anyone tried extendedcode with edge devices?
