I have an app that uses ORM rather extensively. For the most part it works like a charm. I only have an intermittent error that seems to occur exclusively when the app is accessed on an iPad using data (as opposed to WiFi).
I have users accessing this app in the field and occasionally they will get that obnoxious "Mapping for component (fill in the blank) not found". Only, it was clearly found earlier and if the user logs out and back in, or closes the browser and starts over, the error goes away.
The error throws on a <cfajaxproxy> tag at the beginning of a page load.
