The current design for UI widgets intermixes the logical and visual aspect of attribute handling. They should be split into 2 concepts:
- Field: field is responsible for loading, storing, and validating the values, getting metadata info (e.g. data type, validation pattern, I18n label), checking the permissions, etc.
- Widget: the new widget will be responsible for displaying the values, saving user input, detecting keystrokes, showing undo buttons, showing error messages, etc.
