From 202790a07db3a8eaf0ac2ab3d8cd755c473eb345 Mon Sep 17 00:00:00 2001 From: Kyle M Hall Date: Mon, 20 Nov 2017 11:05:35 -0500 Subject: [PATCH] Bug 19655 - To.json doesn't escape newlines which can create invalid JSON Content-Type: text/plain; charset=utf-8 JSON does not allow real line-breaks. If a field contains them and they are not escaped, a JSON parser will be unable to convert the stringified JSON back into an object. This is clearly exemplified by the guarantor search, where a multi-line note on the guarantor's record will break the ability to select that guarantor. Test Plan: 1) Create Patron A with a "Circulation note" that has multiple lines in it 2) Create Patron B 3) Attempt to set Patron A to be the guarantor for Patron B 4) Note selecting the patron does nothing 5) Apply this patch 6) Repeat step 3 7) Selecting the guarantor now works!
