method: cfajaxproxy, cfc and js class library

Have you looked in Firebug? Have you checked the Firebug console, to
watch the call being made, and the result being returned? In FF, did you
place a console.log(id) as the first line of your passIdOn() method, to
see if it was being called and what it was being passed?

OK, you have part of the battle. That tells you what the cfc is doing,
what the server is returning. The callback wouldn't be a part of this
information. Setting the callback function registers it within your
browser client, as a listener action to take when a return value is
received.

is, the built-in spell checker was disabled by FckEditor.

following line:
FCKConfig.FirefoxSpellChecker = true;

I'm not exactly sure if a business function has to go that route...
And I agree with Warrent that Stored Procedure, be it MS SQL Server or Oracle
or IBM DB2, would help with performance substantially (for one thing, sql

Good thought, cleared FF2 cache still to no avail. Will find another box that
has FF2 to try again. Thanks.
Have you cleared your browsers cache? Any changes to the FCKEditor config
file require browswer cache flush to take effect...

Great ideas, many thanks. The 'this' replacement for

Yes, my FF2 has Firebug installed, I did not see any error, previously if there
were CFC or JSON problem it
I'm curious to know, if we are able to not load some of the stuff that a given

So, the idea is similar to enable/disable certain CF tags via its admin
function (for security) or even via some XML config file but
