Hi

I currently have the same issue with jQuery v1.7.1 and even 1.7.2 beta 2!

I get a permission denied error when trying to submit a form using jQuery for line 1703

id = isNode ? elem[ internalKey ] : elem[ internalKey ] && internalKey,

Reverting back to jQuery v.1.6.4 seems to work for now

Thanks

Hi again!

Created a try catch around the permission denied issue for IE7, and set the id and isEvents vars to false by default

If anyone wants to try this for now this will help with the issue within jQuery v1.7.1+ (including v1.7.2 beta 2)

		var privateCache, thisCache, ret,
			internalKey = jQuery.expando,
			getByName = typeof name === "string",
			id = isEvents = false,

			// We have to handle DOM nodes and JS objects differently because IE6-7
			// can't GC object references properly across the DOM-JS boundary
			isNode = elem.nodeType,

			// Only DOM nodes need the global jQuery cache; JS object data is
			// attached directly to the object so GC can occur automatically
			cache = isNode ? jQuery.cache : elem;

			// Only defining an ID for JS objects if its cache already exists allows
			// the code to shortcut on the same path as a DOM node with no cache
			try {
				id = isNode ? elem[ internalKey ] : elem[ internalKey ] && internalKey;
				isEvents = name !== undefined ? (name === "events") : isEvents;
			} catch(e) {
			}

Would be great if this could be fixed for the next release!

Inserting try/catch is not really an option. It inhibits debugging and hides the actual problem. I don't see a reason to reopen this ticket until we have a small test case that can reproduce the issue, but I'd be willing to investigate further once we do have a test case.

I get this too when using an iframe and a different subdomain for performing ajax requests. What's the best way to debug this? It seems to be related to event handling, as it only happens when name is "events".
