Subject: Support labelFormat for read-only AutoFieldWidget's
X-Git-Tag: sprint4-merge-nov22~5201
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=cb3125afa53716ae6642e5510e37a92f79f1ed53;p=working%2FEvergreen.git

Support labelFormat for read-only AutoFieldWidget's

Previously only worked with edit widgets (e.g. drop-downs).  This also
takes into account the fact that different instances of AutoFieldWidget
for the same class and value may have different labelFormat's

One user-visible result of this change is the ACQ read-only fund display
in purchase orders.  Funds will now show the code and year for funds in
the copy grid before and after the data is rendered read-only.
