Subject [jira] Created: (MYFACES-467) Add ability for credit card validator to choose card type based on another component

Add ability for credit card validator to choose card type based on another component

         Key: MYFACES-467
     Project: MyFaces
        Type: Wish
  Components: Tomahawk  
 Reporter: Ken Weiner

It would be nice if the credit card validator could, in one of its attributes, optionally
specify the ID of another component, whose value should be used to determine which card type
should be used in the validation.  This would come in handy for forms that have a select-one
component with a list of credit card types.  I would think that forms with both card type
and card number are common.

Example of tags:

<%-- Credit Card Type --%>
<h:outputLabel for="cardType" value="Credit Card Type"/>
<h:selectOneMenu id="cardType" value="#{backingBean.cardType}" required="true">
     <f:selectItems value="#{backingBean.cardTypeSelectItems}"/>

<%-- Credit Card Number --%>
<h:outputLabel for="cardNumber" value="Credit Card Number"/>
<h:inputText id="cardNumber" value="#{backingBean.cardNumber}" required="true">
    <t:validateCreditCard forCardType="cardType"/>

The code would have to make an assumption about what values from the card type map to which
credit cards.  The values amex, visa, mastercard, and discover seem appropriate.

I may get around to adding this ability, in which case I will attach the patches here.  If
I don't, though, I wanted to capture this suggestion in case someone else wants to do it.
