I'm learning Flash Remoting by working with the Real Estate sample app on the
CF Developer Center. Everything works fine, except that if I make a change to
the CFC that accesses the database (such as changing the query, etc), it has no
effect in the applicationunless I stop/start the CF Server service. I can
reload the home page (and get the "initializing" message), start a new browser
session - nothing shows me the change unless I restart the CF service. The CFC
is instantiated in Application.cfm inside a <cffunction
name="OnApplicationStart"> tag.

It's as if the CFC is cached, and a new instance is not being created when I
reload the page, or even if I restart the browser.

There must be a way around this - otherwise each edit/test cycle is VERY
tedious - I must be missing something - help!

Thanks,
Robert

Robert -

Your issue is not the CFC. I know of only two ways to get the new
Application information into use. One, wait a LONG time. Two, stop and start
CF. Can you invoke this CFC outside of OnApplicationStart? hth

HI Brian - meant to get back to you yesterday - thanks for the tip - that led
me to a better understanding of what is really going on. I've used CFC's, but
never loaded them in the Application scope - that's why I couldn't understand
the behavior.

Thanks,
Robert

Robert,
The CFC is cached in the application scope when the application gets
initialized.
If you are making changes to the cfc, you can move this line in
Application.cfc:
<cfset application.listingGateway =
createObject("component",variables.componentPath &
".components.ListingGateway").init(variables.dns) />

to the onRequestStart function, a couple of lines below it (line 20).
By doing that, you will instantiate a new component every time you call a page.
I recommend that you put it back when you are finished.

Cheers,
Laura

Laura - Thank you so much. I had a misunderstanding of the duration of the Application scope.

Regards,
Robert
