Thanks Steve, Jay, Clark and Axunderwood for the prompt responses and useful
suggestions.
1. I have changed the return typeof 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

Subject: Re: [ACFUG Discuss] newbie question: storing an array variable into a
variable whose data type is not specified
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...
