[open-ils-commits] r14879 - trunk/Open-ILS/xul/staff_client/chrome/content/OpenILS (phasefx)

[svn at svn.open-ils.org]

Author: phasefx
Date: 2009-11-12 01:03:26 -0500 (Thu, 12 Nov 2009)
New Revision: 14879

Modified:
   trunk/Open-ILS/xul/staff_client/chrome/content/OpenILS/global_util.js
Log:
Turn off bubbling for the oils_persist event (makes things less noisy with iframes, etc.).  Support @oils_persist_peers for persisting related elements (mainly to support radio group style widgets)

Modified: trunk/Open-ILS/xul/staff_client/chrome/content/OpenILS/global_util.js
