RE: [flexcoders] Re: calling a cfc from flex
Hi again,
When using query as return type you don't need to set columnName in your
datagridColumn in uppercase. Uppercase is just when referencing to structures
returned from coldfusion.

Subject: [flexcoders] Re: calling a cfc from flex
First of all I want to say thanks for your help on the last few
posts. I think I am almost there.
I have my CFC now returning a query and have eliminated all errors.
But, when I trigger my click event it seems to return the query in my
DG however no text is visible (when you scroll over the DG it
highlights each item, but not text is visible).
Also, since I am now returning a wuery I no longer need to loop over
query result and insert each record into an individual structure and
append that to an array...correct? (or is that still necessary?) I
did configure my CFC both ways though and got the same result...a DG
with no text, but obvisouly filled with somthing do to highlighting.
I have posted what I have so far.
Thanks,

RE: [flexcoders] Re: calling a cfc from flex
The error is the type you returned. You typed as string when its or an array
(of structs) or a query. Even in CF you'll have that error it's not on the Flex
side the problem, is your return type in your CFC.

OK, I glad to know there is a way to just return a straight query
from a CFC...that is good to know. I did change my columnName in my
DG to all caps (is this still necessary in MX7?) and made changes to
my ActionScript code, however I am still getting a "value from
getPersonnel() of not type string" error.
Do I no longer need an array of structures in my CFC, and just return
a query result? Or, do I still need to put the results of the query
into an array of structures? I did try both ways however in my CFC,
and am still getting the same error regardless.
This is what I have:
getPersonnel.cfc
SELECT *
FROM dbo.ItemsInvolvedLOV
personnelNeeded.MXML
Remote Object
http://IPADDRESS:PORT#/flashservices/gateway";
source="cfdocs.components.getPersonnel"
fault="mx.controls.Alert.show
(event.fault.faultstring, 'Error')"
showBusyCursor="true">
