Subject: LP#1832897: improvements to eg-fm-record-editor
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=d8986fc8ea35f349a1c15aee25cb748159ef09d5;p=working%2FEvergreen.git

LP#1832897: improvements to eg-fm-record-editor

* Add a new optional attribute, preSave, for passing a
  callback to modify modify records (e.g.,
  to provide default values) before they are saved.
* Ensure that the components current copy of a record is
  discarded when the user closes or dismisses the modal

  This addresses an issue where editing multiple instances
  of records on an admin page could display (and/or flash)
  stale data, particularly for the new multi-select widget.
