Binding a control to a cfc with multiple triggers

Question

I'm an old-school coder. I've been trying to figure out the
new AJAX controls to see if they could save me some time, but I'm
running into headaches.
At the moment I'm building a tool to reconcile a table full
of firstname lastname and organization records (strings, no id's)
with 2 other tables that contain organizations and contacts,
respectively. IOW, we're trying to match string data with records
that have ID's.
My tool so far has 3 form fields per record - a "this is
valid" checkbox and 2 select lists. One for organizations, second
for the contacts associated with that org. On load, I bind the org
select to a CFC that attempts a direct lookup using the string
value of the record, then a SOUNDEX match. Now, when the select
list gets loaded, I want to use the first matched record's ID to
lookup contacts for that org. How do I tell the second select list
to wait until the first one is loaded before doing its lookup, and
to do another lookup anytime that value changes? What if I wanted
to also link the lookup functionality to the checkbox 's onChange
event? I may want to add a separate checkbox so there is one for
org and one for contact in case an org exists but the contact
doesn't.

1) in your contacts cfselect make sure you have specified
bindonload='false' - this will prevent it from loading any
data on
pageload, before an entry in your organisations list is
selected
2) in its bind argument add @change to the bind parameter:
i.e.
bind='cfc:path.to.your.cfc.method({formcontrolname@change})'
- this will
make it re-lookup data on each change in the organisations
list (it may
be that @change is even default event, so you may not even
have to add
it at all... can't remember now if it is change or click that
is default...)
3) how do you want to link your select lists to your check
boxes? what
action should the change in the state of a checkbox trigger?
