static final java.lang.String defaultCommandClassName
Default implementation class for this command.
This method returns the member ID to whom to send the e-mail. The default
implementation tries to find a registered user associated with the current
personalization ID. If none if found, then it tries to find the latest guest
user associated with the personalization ID. If none is found, then it returns
the current member ID. A customization could override this method if the member
ID may not be associated with the personalization ID, for example, to send
the e-mail to the Account Representative associated with this users B2B account.
Another example is that a specific Sales Representative should be send an e-mail
that the customer has places an order for over $100,000.
This method returns a member ID to which the e-mail should be sent. If null
is returned, then no e-mail will be sent.
