This is how you will do it
<mx:DataGrid dataProvider="{people_info}" .....>
.....
</mx:dataGrid>
In the actionscript, you will do
[Bindable]
private var people_info:ArrayCollection;
people_info = eventObj.result.people_info as ArrayCollection;
as the result from your cfc contains three elements
people_Info
statMsg
status

Thanks Steve, Jay, Clark and Axunderwood for the prompt responses and
useful suggestions.
1. I have changed the return type of function to "struct" and other
changes in the function as below according to the suggestions
<cffunction name="myfunction" access="remote" returntype="struct">
<cfargument name="form_data" type="struct">
<cfset var result = StructNew() />
<cfset var person = "" /> <!--- Why is this needed? I did not understand
this part. I realize the concept is to initialize variables with blank
values before using them --->
<cfset result['dept_name'] = "some dept"
<cfset result['dept_num'] = "some dept number"
.
.......
<cfscript>
ArrayAppend(peoplearray, #printPeople.empID#);
ArrayAppend(peoplearray, #printPeople.departmentname#);
ArrayAppend(peoplearray, #printPeople.departmentID#);
ArrayAppend(peoplearray, #printPeople.empTitle#);
</cfscript>
. <cfset result['people_info'] = peoplearray
<cfset result['statMsg'] = 'Information successfully
collected.'>
<cfset result['status'] = true>
<cfreturn result>
</cffunction>
Rest of part is same as I posted earlier
2. How would I reference the return values in the caller function which is
a Flex component?
private function myfunction(eventObj:ResultEvent):void{
var people_obj:Object = new Object();
people_obj.dept_name = eventObj.result.dept_name;
people_obj.dept_num = eventObj.result.dept_num;
// would the below code work?
people_obj.peoplearray = eventObj.result.peoplearray
}
// How can I access the department name, department ID and employee ID,
title of the third person whose name is John from the above people_obj //
object?
// Or, do I need an arraycollection variable
[Bindable]
private var people_info:ArrayCollection;
people_info = eventObj.result.peoplearray
Then, I could load the arraycollection variable people_info into a
DataGrid element where the elements would be displayed in order?
Can someone please advise?
Thanks

yep, what you are actually doing is creating a named struct (hash) when
you do this:
<cfset result['people_info'] = peoplearray />
changing the return type will give you exactly what you want (unless you
want an array), and if you do then you can create an array of structs...

Hi All,
I am a newbie to Coldfusion. My development background is mainly in C/C++
so please excuse me if my below question is naive.
I have a function as below
<cffunction name="myfunction" access="remote" returntype="any">
<cfargument name="form_data" type="struct">
<!--- The variable to be returned by the function is "result" --->
<cfset result['dept_name'] = "some dept"
<cfset result['dept_num'] = "some dept number"
<!--- I run a query where I want to find some information about people
having
name "John" and there can be N number of people with the name of John --->
<cfquery dbtype="query" name="printPeople">
SELECT *
FROM people
WHERE peopleName = "John"
</cfquery>
<cfset peoplearray=ArrayNew(1)>
<cfset myCounter = 0 />
<cfloop query="printPeople">
<cfset myCounter = myCounter + 1 />
<cfscript>
ArrayAppend(peoplearray, #printPeople.empID#);
</cfscript>
<cfscript>
ArrayAppend(peoplearray, #printPeople.departmentname#);
</cfscript>
<cfscript>
ArrayAppend(peoplearray, #printPeople.departmentID#);
</cfscript>
<cfscript>
ArrayAppend(peoplearray, #printPeople.empTitle#);
</cfscript>
</cfloop>
<cfset result['people_info'] = peoplearray <!--- Can this
be done? --->
<cfset result['statMsg'] = 'Information successfully
collected.'>
<cfset result['status'] = true>
<cfreturn result>
</cffunction>
The part <cfset result['people_info'] = peoplearray
attempts to store an array variable into a variable whose data type is not
specified.
Can this be done?
If not, what should I do? Should I define the datatype of "result"
variable as a structure, change the return type
in function signature as a structure from any as a structure variable
can hold string, integer and array variables?
Any suggestions would be appreciated.
