Hello.
After installing UR12 I found the issue with Xrm.Page.Ui.addCustomView method in IE10 and Firefox/Chrome. It still using selectSingleNode() method after getting ajax response (see the picture below). It happened inside CRM code javascript code, I can't find it and fix. Could someone, please, suggest me the workaround? At now, I forced to remove all custom view from lookups, and it makes users unhappy.
Thanks.
