[~michpetrov] sorry for the wrong accusation then! - FireBug wraps the search trough all
JS files...
So the problem can be worked around as we did with limitRender="true" fixed on
rich:tree. But the original problem in the combination RF+Mojarra still remains if you
omit to do this on every AJAX-request. This has the downside, that if you actually want to
have some (valid and visible) components being re-rendered on an AJAX request without
specifically adding those IDs to the rendered-attribute everywhere throughout the
application, you can't do it anymore. As I mentioned, that leads to other problems...
The source of the problem being located in jsf.js means that this is originally bad
handling by Mojarra?! - or is it just something that only happens because RF introduces
the possibility of some components being automatically re-rendered after AJAX-Requests
(like rich:message/s, a4j:outputPanel etc.)?
Will you be looking into the main issue as well? - maybe in cooperation with the guys from
Mojarra? - or do we have to file a bug report at Mojarra - which would mean back to square
one...

Random JavaScript error due to missing attribute
'richfaces.RICH_CONTAINER'
---------------------------------------------------------------------------
Key: RF-13780
URL: https://issues.jboss.org/browse/RF-13780
Project: RichFaces
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: component, component-tree
Affects Versions: 4.3.7
Environment: RichFaces 4.3.7
Mojarra 2.1.29
Java 7 Update 67 (x64)
Tomcat 7.0.52 (x64)
Firefox 31
Reporter: Michael B
First of all: this is a bug report which may be related to RF-13776, since it also
originates in the same spot of the JavaScript library of RichFaces.
Preface:
The problem is difficult to reproduce systematically, since it only seems to occur in one
of n cases of loading one and the same complex xhtml (with exactly the same data from the
backing bean).
The problem is described based on the rich:tree component when clicking on the expand
icon of a treeNode which fires a "ToggleEvent".
Occasionally there is a JavaScript error in the last line of
{code}
richfaces.ui.TreeNode.emitToggleEvent = function(nodeId) {
var node = document.getElementById(nodeId);
if (!node) {
return;
}
richfaces.$(node).__fireToggleEvent();
};
{code}
When the problem occurs, the expression {code}richfaces.$(node){code} evaluates to
'undefined'.
Debugging into the function when the problem occurs:
{code:title=richfaces.$|borderStyle=solid}
richfaces.$ = function(source) {
var element = richfaces.getDomElement( source );
if(element)
{
return( element[richfaces.RICH_CONTAINER] || {} )["component"]
}
};
{code}
While the element is correctly evaluated to the treeNode/treeNodeToggle-source, the
expression {code}element[richfaces.RICH_CONTAINER]{code} evaluates to
'undefined'.
Reloading the page one or more times produces correct results, where the attribute is
set.
To be able to provide a reproducable example of the problem, please provide some
information under which circumstances the property may not be set correctly for some
components. Please also give us a hint, where to debug into the RF JavaScript code to find
the spot where this property is set.
Although the problem doesn't occur all the time, it happens quite often with the
effect of breaking the entire application. So for future versions I would suggest a check
if {code}richfaces.$(xyz){code} evalutes to a valid result, before invoking any operations
on the result and maybe write a message to the a4j:log in cases where a valid result is
expected but not returned.
