---------------------------------------------------------

[~michpetrov], thanks - but we are not using maven in our projects for good reasons! - Just replacing some jars is also fine and not the problem. However getting a complex application to work and re-testing dependencies is. 
We will try to see if we get it running, but looking at all the problems we've encountered with JSF until now, I doubt it will be easy ...

>             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

> 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.
