An advantage with the current dialog.data bean is that it allows a the
use of a common view when the underlying data objects are different. How
would this be done with dialog managed beans?
As an example the AbstractPayment class has a CreditCard and a Check
implementation. Both the "Pay By Check" and "Pay by CreditCard" share a
common view that collects the billing address information. In the
current implementation, that view uses #{dialog.data.billingZipCode} to
pass the billing zip code regardless of the actual class. With dialog
managed beans their will be a check and creditCard bean so how would the
billing zip code be referenced in the common view? So unless their is a
way to alias the beans in the dialog configuration, the billing address
view can not be shared.
Dialog configuration show the common view getBillingAddress.
<dialog name="Pay By CreditCard" start="getBillingAddress">
<view name="getBillingAddress" viewId="/getBillingAddress.jsp">
<transition outcome="next" target="getCreditCardNumber"/>
</view>
<view name="getCreditCardNumber viewId="/getCreditCardNumber.jsp">
<transition outcome="next" target="processPayment"/>
</view>
<action name="processPayment" method="#{creditCard.processPayment}">
<transition outcome="success" target="paymentAccepted"/>
<transition outcome="rejected" target="paymentRejected"/>
</action>
<end name="paymentAccepted" view="/paymentAccepted.jsp"/>
<end name="paymentRejected" view="/paymentRejected.jsp"/>
</dialog>
<dialog name="Pay By Check" start="getBillingAddress">
<view name="getBillingAddress" viewId="/getBillingAddress.jsp">
<transition outcome="next" target="getAccountNumber"/>
</view>
<view name="getAccountNumber viewId="/getCheckingAccountNumber.jsp">
<transition outcome="next" target="processPayment"/>
</view>
<action name="processPayment" method="#{check.processPayment}">
<transition outcome="success" target="paymentAccepted"/>
<transition outcome="rejected" target="paymentRejected"/>
</action>
<end name="paymentAccepted" view="/paymentAccepted.jsp"/>
<end name="paymentRejected" view="/paymentRejected.jsp"/>
</dialog>
