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
Environment: tomcat 6, facelets, RichFaces 3.3.1
Reporter: Ryan Yoder
Priority: Minor
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);
}
