Ive searched through the KB but cannot find any information of how to clear a date time field when using actions.
Basically when a CI item is loaned out the following fields are populated on the CI form:
Assignment Type: Perm, loan....
Issued To: Name
Loaned out: dd/m/yyyy hh:mm
Return date: dd/m/yyyy hh:mm
and a few others
When said item is returned the status is changed a "Rebuild" or "In Store" which then runs a quick action and clears all the fields. However I cannot find an expression or action to clear the date fields. There are a couple of articles suggesting the $(null) or $("") may work but unfortunately not (and when used it does not error, basically does nothing).
