Generally, my forms all connect with a bean. If I have a form field for
email, my bean has a getEmail() method on it.
Then, when I submit my form, I use event.makeEventBean( FormBean ,
"list,of,form,fields,to,shove,in,the,bean") to populate the bean with the
values from the event.
Once I validate, and find errors, I simply add a result that goes back to
the form.
The form once again only talks to the bean, but this time, the bean has the
parameters from the event (what the user typed into the form).
<cffunction name="doSendMessage" access="public" returnType="void"
output="false">
<cfargument name="event" type="any">
<cfset var UserMsg = arguments.event.getValue("UserMsg") />
<!--- populate the bean with the submitted form values --->
<cfset var messageBean = arguments.event.makeEventBean( "MessageBean",
"ActivityID,ChallengeID,InvitationID,MemberID,Message,ReplyToMessageID,TeamID")
/>
<cfset var resultToAdd = "failure" />
<!--- validate and save if the bean is quality --->
<cfif messageBean.validate() IS true>
<cfset beans.messageHandler.save( messageBean ) />
<cfset resultToAdd = "success" />
<cfif setSuccessMessage IS true>
<cfset UserMsg.addSuccess( "You sent: #messageBean.getMessage()#" ) />
</cfif>
</cfif>
<!--- add the appropriate result --->
<cfset arguments.event.addResult( resultToAdd ) />
</cffunction>
Thus completes the circle.
