[CLOSED][ext-core-svn74] Ext.lib.Event.purgeElement causing error

[woomboom]

Using code from svn @ r5496 I am seeing an error that happens often. It breaks in Ext.lib.Event.purgeElement saying l is null. I applied the following override to fix:

Ext.lib.Event.purgeElement = function(el, recurse, eventName) {
	var me = this,
		i, l, v, len;
	l = me.getListeners(el, eventName) || []; 
	for (i = 0, len = l.length; i < len; i++) {
		v = l[i];
		if(v) {
			me.removeListener(el, v.type, v.fn, v.idx);
		}
	}

	if (recurse && el && el.childNodes) {
		for (i = 0, len = el.childNodes.length; i < len; i++) {
			me.purgeElement(el.childNodes[i], recurse, eventName);
		}
	}
}

Can you post a simple test case to demonstrate the issue?

Ext-core svn77 resolves this issue. But in the future, please include a test case as Evan stated.

I ran into this problem as well, but unfortunately r77 doesn't fix it for me. However the below patch does:

        removeListener : function(element, eventName, fn, scope){
            var el = Ext.getDom(element),
                f = ((el && elHash[el.id]) || {})[eventName] || [],
                wrap, i, l, k;

I'm sorry I don't have the time to make a test case. My problem occurred when an Ext.Window (containing a FormPanel with a GridPanel and some combo boxes) was closed using the X.

Best regards,

Tommy ran into this today as well and it fixed that in svn79.
