Hello.
I made some changes to payment modules to be not displayed and choosed by customer, when (for example) total order amount is higher, than x amount.
Or, when you choose to store pick-up, there is no need to display COD option.
I made changes in __construct code and in check() function.
But it dosnt work with OPC - it works fine after reloading whole page, but does not, after just checking radio buttons, ie :
when i check "store pick-up", option COD is still showed. When i push F5, COD option disapears.
