Hi List, I am struggling with a simple backtrack scenario with our web- site shopping cart.

To observe the behaviour, please use this link to put a delightful pair of gloves in the cart on our test server:

http://test.inrax.com/wa/4/43/4004/120494.html

then click CHECKOUT, enter some rubbish into the mandatory fields and TICK THE "Deliver to an alternative address?" box, then click NEXT STEP.

This takes you to the next checkout page where you can enter the alternate delivery address.

Now you realise that you don't want a separate delivery address after all, so you backtrack one page and untick the "Deliver to an alternative address?" box and click NEXT STEP again.

This is where things go wrong and the behaviour depends on the browser:

Safari on Leopard: the new toggle selection is completely ignored and your second click on NEXT STEP does not result in my submitDetails() method being called at all; this is the action method on the NEXT STEP WOSubmitButton. Tellingly (I suspect), if you do the opposite and initially do NOT tick the Alternate Delivery Address toggle, but change your mind, backtrack and then tick it, the submitDetails() is called and it works as expected.

IE8 on WinXP: When you try to backtrack, IE doesn't let you, saying: Webpage has expired, Most likely cause: The local copy of this webpage is out of date, and the website requires that you download it again. etc. and if you opt to refresh it tells you not to do so if you are buying something!

Firefox on Leopard: On clicking the backtrack button, you are told Firefox must send info to repeat the action and clicking Resend has the end result of leaving you where you are effectively blocking the backtrack.
