Problem (IE) with document.wwv_flow.f01.length after upgrade 4.1.1.00.23.

Question

In case anyone has had this issue (or is about to), there is a new bug after the upgrade to 4.1.1.00.23 with tabular forms and using document.wwv_flow.f01.length during onload. Seems to happen with Internet Explorer 7 or 8. Doesn't happen with the versions of Firefox nor Chrome that I have and also didn't happen with IE prior to the upgrade.
Check it out here (simple example uploaded to apex.oracle.com):

First try it with Firefox or Chrome.
1. Go into the page.
2. You should get a popup telling you the number of rows.
3. Hit 'add rows'. You should get a popup telling you the number of the nth row that you just added.
Now try it with IE and see what happens. #2 doesn't work anymore. Instead it's some alert box with junk in it for some function declaration not even on my page! Probably coming from the Apex library somewhere.
Why do we care? Well most of us probably don't, but in my case in my real app I evaluate document.wwv_flow.f01.length in order to do some conditional javascript processing and that gobbledygook messes it all up.

Hi,
You need to pass the array length into the onload call, so just amend the onload call like this
if (window.addEventListener) // W3C standard, for Firefox, Chrome, etc.
  addLoadEvent(InitDetailItems(document.wwv_flow.f01.length));
else if (window.attachEvent) // Internet Explorer
  addLoadEvent(InitDetailItems(document.wwv_flow.f01.length));Thanks
