Input and output parameter. As input, name of the list to create on output with the following columns:

Description

The legal values returned by cart:getlegalvalues may be supplied by Transact, and may be incomplete until the cart is checked. No list is created if the cart has not yet been checked, or if there are no fixed possibilities for the parameter.

Example

<!-- Get the current cart. -->
<commercecontext:getcurrentcart varname="thiscart"/>
<!-- Check the cart to enumerate payment methods. -->
<cart:check name="thiscart" varname="cartstatus"/>
<!-- Now get the legal values for the payment types. -->
<cart:getlegalvalues name="thiscart" field="paymentInfo-brandID"
listvarname="paylist"/>
