I'm going to have to cry foul on this. It *is* possible, but it
requires some creativity.
1. Create your special decorator object.
2. Create a single instance of this object and add it as a listener
for the AfterNewTransferEvent.
3. Implement the actionAfterNewTransferEvent() method such that it
mixes the two components together and does setup.
AutoDecorator.cfc:
<!---+
Mix the two components together. Only mixes the public stuff, so if
you need private methods or
variables you'll need to inject another method and use that.
--->
<cffunction name="actionAfterNewTransferEvent" access="public"
returntype="void" output="false">
<cfargument name="event" type="transfer.com.events.TransferEvent"
required="true">
<cfset var object = arguments.event.getTransferObject()>
<cfset object.mixin = mixin>
<cfset object.mixin(variables)>
<!--- Maybe call some special method like setup() here to allow the
special decorator to do setup --->
</cffunction>
<cffunction name="mixin" access="public" returntype="void"
output="false">
<cfargument name="componentVariables" type="any" required="true">
<cfset structAppend(this,componentVariables.this,false)>
<cfset structAppend(variables,componentVariables,false)>
</cffunction>
In general I'm a big advocate of very dynamic solutions, but this
seems rather extreme with a high cost in terms of maintainability
later. So, while this does work, I'd argue that it'd be better to just
use decorator="BaseDecorator" on every <object/> in your transfer.xml
instead of this much black magic.
