From a00712e95133001b29fb15b15ccb6e66f2ec075b Mon Sep 17 00:00:00 2001 From: Mike Antipov Date: Mon, 26 Apr 2010 17:19:43 +0300 Subject: Fixed major bug EXT-6092 [crashhunters] Crash in LLFlatListView::selectItemPair Reason: A) incorrect UP arrow handling in accordion control: invisible accordion tab was selected to handle selection. B) invalid std::map item (in empty map) was used to make selection in Flat List Fix: added checks against empty map before use front/back item pair before selecting first/last items. Also updated processing of the UP key in accordion control to not select invisible accordion tab.
