Michael B created RF-13780:
------------------------------
Summary: 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.
