Paypal payment problem

[GoogleCodeExporter]

e-commerce version: 3.1 23/10/2013

SilverStripe version: 3.1 from github

I created a paypal sandbox and have initialized the values ​​according to 
your information:

if(Director::isDev() || Director::isTest()){
    PayPalExpressCheckoutPayment::set_test_config("TestPaypalAPIUsername","TestPaypalAPIPassword","TestPaypalSignature");
}
elseif(Director::isLive()){
    PayPalExpressCheckoutPayment::set_live_config("PaypalAPIUsername","PaypalAPIPassword","PaypalSignature",false);
}

When I try to make a payment using the button 'Place order and make payment' is 
displayed the error that I have indicated in issue 594, but immediately 
disappears the error and displays the link:

http://www.sendasoft.com/en-us/checkout/order-confirmation/showorder/938/

No are requested the buyer data through paypal.

In sandbox not shown anything.

And in http://www.sendasoft.com/en-us/checkout/order-confirmation/showorder/938/

is displayed payment status: Pending

Date    Payment Status  Method  Note    Amount
23/10/2013 20:25    Pending     Paypal Credit Card      €381.79

What is happening?
I need help to make this work.

Thanks Nicolaas,

Jose A.

The issue 594 has not been solved and will surely be the reason why it does not 
work paypal.
Maybe solving this problem (604 or 594) will be solved the problems 596 and 604.
