A multi-valued text widget has been created to replace the old
IPA.details_field. The old code was designed to handle all data
types, and it uses one <dd> tag for each value, so the code is
still incomplete and complex. The new code was designed to handle
only multi-valued text attributes, and it uses one <dd> tag for
all values, so it's easier to maintain. There are already other
widgets that can be used to handle other data types.
The new code supports line-level undo and line-out for removal
like the old code, but there are some changes:
- Undoing a newly added line will remove the entire line.
- Editing the value of a removed line will cancel the removal.
- It provides 'undo all' link to reset the entire attribute.
The old code will be cleaned up in a subsequent patch.
