doPostBack Failure With Safari 5.1.4

Our bank's website uses a _doPostBack JavaScript "link" to open a clicked account's transaction page, but Safari 5.1.4 seems to kill this functionality. Clicking the link does nothing -- it never registers at all. Here's the link format:

javascript:__doPostBack('ctl00$PageContent$ctl00$_acctsBase$_depositsTab$_deposi tsGrid$ctl03$_designator','')

The WebKit Nightly Builds work perfectly. I have reported the issue, as well -- just wondering if anyone else has run into this and found a workaround. And yes, JS is fully enabled and working.

I am experiencing the same issue with may bank's online website and Safari 5.1.4. _doPostback... fails. Chrome and Firefox both work.

I did ensure that Safari is opening in 64-bit mode as was mentioned on other threads.

I guess this is what I am seeing as well. When I try and login to my Mellon account it fails on the second screen. I did not know what was going on but it sounds like this. I have reported to Apple as well. I tried an old machine with Safari 5.0.4 and it works fine.

I have the same problem with the City of Berkeley Building Permit Status website. The link fails under Safari 5.1.4 and also fails under Firefox 11.0. It works on an old Power PC Mac running Safari 4.1.3.

So if you have an old Mac, I guess that's a workaround.

More info: just tried it using Safari 5.1.4 on an iMac 6,1 and on an iMac 8,1 and it worked OK on both of them. Does not work on my MacBookPro.

Safari 5.1.5 exhibits the same behavior. Latest WebKit still works fine, though.

Just a thought by way of possible workarounds ... are the affected customers able to get past the trouble if they log on using a different user agent?

To get access to the User agents via the Develop Menu, go into your Safari advanced preferences and select "Show develop menu in menu bar":

Changing the user agent to Safari for iPad worked, I tried Internet Exporer 8.0 and that did not work. What is the consequence of using an alterante user agent?

This is so odd...

- Suddenly, my 5.1.3 install on my Mac Pro quit doing the doPostBack. TOTALLY random.

- I went ahead and upgraded to 5.1.5, same issue.

- I changed the User Agent to *anything* except Safari and it worked.

- I changed the User Agent back to Default/Automatic, and it worked. ???

- I Quit and Closed All Windows, leaving the UA Default -- and it still worked.

At this point, the issue is resolved somehow by merely changing the UA. I don't know if there's a cookie or something stored and the UA really isn't being released... ???

No matter what I do in Safari, user agent canges or anyting it still does not work with my Mellon account log in. Google Chrome works fine as does Firefox. I have sent Apple the failed pages many times but no response yet. When I tried Safari 5.0.4 on an old machine it wokred just fine so Apple has broken something.
