When you call the CFC via cfajaxproxy, nothing is calling
init().
This is something that catches a lot of people out when they
first
start writing remote access CFCs. The remote access CFCs are
constructed on each remote call and the method called and
then the CFC
is thrown away.
A typical idiom in this situation is to have your application
create
and initialize your CFC and store a reference in, say,
application
scope.
Then your remote access CFC (the one you call via
cfajaxproxy)
delegates method calls to the same named methods on the CFC
in
application scope:
<cffunction name="doSomething" access="remote">
<cfargument name="data"/>
<cfreturn
application.modelCFC.doSomething(arguments.data) />
</cffunction>
where application.modelCFC is the CFC you've created and
initialized,
passing in DSN and date.
Hope that helps?
