// Currently has the following issues:
// - Does not handle postEditValue
// - Fields without editors need to sync with their values in Store
// - starting to edit another record while already editing and dirty should probably prevent it
// - aggregating validation messages
// - tabIndex is not managed bc we leave elements in dom, and simply move via positioning
// - layout issues when changing sizes/width while hidden (layout bug)
