a4j_3_1_GA, PrototypeScript null error in IE

vh Jun 16, 2008 6:56 PM

In a4j_3_1_GA, PrototypeScript, the following code:


if (window.RichFaces && window.RichFaces.Memory) {
 window.RichFaces.Memory.addCleaner("prototype", function(node) {
 var eventID = node._eventID;
 if (eventID) {
 var cache = Event.cache[eventID];

 for (var eventName in cache) {
 var wrappers = cache[eventName];
 var domEventName = Event.getDOMEventName(eventName);

 wrappers.each(function(wrapper) {
 if (node.removeEventListener) {
 node.removeEventListener(domEventName, wrapper, false);
 } else {
 node.detachEvent("on" + domEventName, wrapper);
 }
 });

 cache[eventName] = null;
 }

 delete Event.cache[eventID];
 }
 });
}

The wrappers.each(function(wrapper)), wrappers is null. So I got a null error in IE only. Firefox show no error. It doesn't prevent you to go on and do the work.

Is there anyway to avoid or fix this error?

The RichFaces is 3.1.4GA.

<html xmlns:jsp="http://java.sun.com/JSP/Page"
 xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:h="http://java.sun.com/jsf/html"

 xmlns:c="http://java.sun.com/jstl/core"
 xmlns:rich="http://richfaces.ajax4jsf.org/rich"
 version="2.0">

We also use our own prototype.js (1.6.0.1) and scriptaculous.js(v1.8.1)

workaround is do not use external libraries you mentioned in order to prevent conflicts.
