I have a couple of users in the field right now collecting point data on two Getac PS236 handhelds, using a bog-standard ArcGIS Mobile deployment. There's maybe seven or eight different fields being collected, half of which are mandatory.
Anyhow, they are experiencing irregular problems when collecting points, the error message being given is shown in the attached JPEG. Apparently if they select 'yes' and recollect the data, it will give them the same error when they try and save it, and the only way to get around the problem is to say 'no', discard the entire feature, and start over again.
I've had a look through the forums to see if this was a commonly-occurring error, but no luck - just wondering if anyone has insights into what might be causing it.
