Elements outside of the modal panel could receive focus using tab key.
----------------------------------------------------------------------
Key: RF-6537
URL: https://jira.jboss.org/jira/browse/RF-6537
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.3.1
Reporter: Sergey Rusak
Elements outside of the modal panel could receive focus using tab key.
According to the current algorithm onfocus listener is added to the very first
focusable element on the page to automatically redirect focus to the first
element on the modal panel. This works fine unless the very first element is
not visible( display='none' in my case). The solution could be adding the
additional check to filter invisible elements(modalPanle.js):
{code:java}
processAllFocusElements: function(root, callback) {
var idx = -1;
var tagName;
if (root.focus && root.nodeType == 1 && (tagName =
root.tagName) &&
// Many not visible elements have focus method, we had
to avoid processing them.
(idx =
this.formElements.indexOf(tagName.toLowerCase())) != -1 &&
this.formElements.charAt(idx - 1) === '|' &&
this.formElements.charAt(idx + tagName.length) === '|'
&&
!root.disabled && root.type!="hidden"
&& (Richfaces.getComputedStyle(root,'display')!='none')
&&
(Richfaces.getComputedStyle(root,'visibility')!='hidden')){
callback.call(this, root);
} else {
if (root != this.id) {
var child = root.firstChild;
while (child) {
if (!child.style || child.style.display
!= 'none') {
this.processAllFocusElements(child, callback);
}
child = child.nextSibling;
}
}
}
}
{code}
