[ https://issues.jboss.org/browse/RF-12860?page=com.atlassian.jira.plugin.s... ] Jan Papousek updated RF-12860: ------------------------------ Summary: Overridng 'Array.prototype.remove' causes JS error when rich:accordion is used (was: AccordionItem.js with error cause browser crash) Description: Put the rich:accordionItem and rich:extendedDataTable on same page, and just click on any column for sort. The firebug will show an error: items[i].__header is not a function [Break On This Error] h -= items[i].__header().outerHeight(); Looks like accordionItem.js line48 been triggered when sort: $(document).one("javascriptServiceComplete", function () { item.__fitToHeight(item.getTogglePanel()); }); And after this happened, my whole thing crashed. Now more sortable or click for any action. ---- *from QA:* When the following code is insterted to the page: {code} <script type="text/javascript"> //<![CDATA[ Array.prototype.remove = function(s) { for (var i = 0; i < this.length; i++) { if (s == this[i]) { this.splice(i, 1); } } }; //]]> </script> {code} and rich:accordion is present, clicking on rich:accordionItem causes the following JS error (from firebug): {code} items[i].__header is not a function [Break On This Error] h -= items[i].__header().outerHeight(); {code} was: Put the rich:accordionItem and rich:extendedDataTable on same page, and just click on any column for sort. The firebug will show an error: items[i].__header is not a function [Break On This Error] h -= items[i].__header().outerHeight(); Looks like accordionItem.js line48 been triggered when sort: $(document).one("javascriptServiceComplete", function () { item.__fitToHeight(item.getTogglePanel()); }); And after this happened, my whole thing crashed.
