TabPanel - Tab - onheadermousedown - onheadermouseup - javascript error - item is undefined -------------------------------------------------------------------------------------------- Key: RF-11999 URL: https://issues.jboss.org/browse/RF-11999 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Environment: RichFaces 4.2.0 CR1 - JSF/Mojorra 2.1.6 - FireFox 10 - Windows 7 - WAS 8.0.0.1 - Spring 3.0.6 Reporter: Jean ANDRE Assignee: Brian Leathem Attachments: index.xhtml, TabOnHeaderMouseDownError.png On rich:tab we use the attribute "onheadermousedown" which call a javascript function defined by a4j:jsFunction. When we switch tab, we got the following error: {code} item is undefined - Line 363 /** * @private * */ __getItemIndex : function (itemName) { var item; for (var i = 0; i < this.items.length; i++) { item = this.items[i]; >>>>> if (!item.disabled && item.getName() === itemName) { return i; } } rf.log.info("TogglePanel.getItemIndex: item with name '" + itemName + "' not found"); return -1; }, {code} The error may be linked to the RF-11763.
