AbleCommerce Shopping Cart Software

Hi

We're developing our own OnePageCheckout and have made many changes. (version 7.0.3)
We're getting a problem with the interaction of the shipping method selector (a radio button list) and the payment buttons that are on the same page.

If I click to change the shipping method, and then complete the credit card details and click the payment button, the card details are cleared and no payment takes place.
Conversely if I click on the payment button with no CC details entered I get the validation messages, and if the next click is on a shipping radio button it has no effect.

My theory is that there is a routine somewhere to stop double clicking on a payment button, but it is being invoked by the shipping buttons as well.

I'm having trouble tracking down the javascript/Ajax functions involved and would really appreciate some pointers on where to look.

Well a wild guess is to check the OnClientClick event processing. In code/ascx file check code against OnClientClick button to figure out the problem.

Yes, thanks, but there's no OnClientClick on the buttons in question. I've now tried creating an alternative button, with no onclink code, and still get the problem, so I think it must be in the form onsubmit code. My problem is finding where it's specified. The source code of the displayed page has a WebForm_OnSubmit() function but I can't fine it in the project code.

Any guesses (wild or otherwise) would be appreciated.
