I prefer:
<event-handler name="Form">
<broadcasts>
<message name="needFormBean" />
</broadcasts>
<views>
<include name="primary" template="form.whatever.cfm">
<value name="XE_handleForm" value="my.form-processor" />
</include>
</views>
</event-handler>
<event-handler name="doForm">
<broadcasts>
<message name="handleFormProcessing" />
</broadcasts>
<results>
<result name="failure" do="Form" />
<result name="success" do="List" redirect="true" />
<result name="customresult" do="IfNeeded" redirect="true" />
</results>
</event-handler>
1. Named results help autodocumentation and also help developers
understand the potential flow of the application without digging through
files
2. Having a separate form and form processing event keeps the logic a
little cleaner and allows for less coupled controllers to the views.
3. Using event.forward() means you either need to pass in the destination
event as an argument to the message (good practice), or a developer must dig
into the controller to find out the flow control (bad practice)
