Extended data table - keyboard navigation of rows of a selectable grid breaks after rerendering another datatable with selectionMode=none ----------------------------------------------------------------------------------------------------------------------------------------- Key: RF-8212 URL: https://jira.jboss.org/jira/browse/RF-8212 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-tables Affects Versions: 3.3.1, 3.3.2.SR1, 3.3.3.BETA1 Environment: tomcat 6, facelets, RichFaces 3.3.1 Reporter: Ryan Yoder Assignee: Nick Belaevski Priority: Minor Original Estimate: 4 hours Remaining Estimate: 4 hours The keyboard navigation of rows of a selectable grid breaks after rerendering another datatable with selectionMode=none. A selectable grid on the top of the pagehas an a4j:support event="onselectionchange" to reRender another grid below it that is showing details about the currently selected row in the upper grid. The lower grid should have selectionmode="none" to produce this bug. The up/down arrows no longer work on the upper grid after the selection is changed and the lower grid reRenders. The problem lies in the following code: ExtendedDataTableSelection.js removeListeners: function() { Event.stopObserving(document, "keydown", this.eventKeyPress); The problem is that for the bottom grid, the this.eventKeyPress is null which has the effect of removing all keydown event listeners on the page, including the top grid's listener. Add an if statement before this line to fix the bug. I have tested it and it works for me. removeListeners: function(){ if(this.eventKeyPress) { // added if to ensure that all keydown event listeners are not removed Event.stopObserving(document, "keydown", this.eventKeyPress); }
