Multiple Payment Methods found the problem

[swissmexxa]

Hi

Thank you very much for this implementation of omnipay for datatrans. You mention that giving multiple payment methods at once will result in a "payment is not valid" message. This is because you send the data in GET Request as &paymentMethod=VIS,ECA instead of &paymentMethod=VIS&paymentMethod=ECA.

In POST Request it is the same. Instead of submitting the form data as paymentMethod=VIS,ECA it should be send with two paymentMethod fields like

paymentMethod=VIS
paymentMethod=ECA

I think therefore the paymentMethod field should be an array and not a string. Would it be possible for you to change your code?

Thank you very much.
