What is the best way to sent the data to coldfusion and then from coldfusion to the database?

The error suggests the Flex client is sending a structure to the function, not an array as you expect.

I've tried to do something like this?

In the flex:

private function submitData():void
{
myService.saveStorages(storages.source);
}

In the CF:
<cffunction name="saveStorages" access="remote" returntype="boolean">
<cfargument name="arrData" type="Any" required="yes">
<cfset i = 1>


<cfloop condition="i LESS THAN OR EQUAL TO #ArrayLen(arrData)#">



<cfquery name="q" datasource="ds">



insert into Storage

values
(
<cfqueryparam value="#arrData [1]#" cfsqltype="cf_sql_varchar">,
<cfqueryparam value="#arrData[2]#" cfsqltype="cf_sql_integer">,
<cfqueryparam value="#arrData [3]#" cfsqltype="cf_sql_varchar">,
<cfqueryparam value="#arrData[4]#" cfsqltype="cf_sql_varchar">,
<cfqueryparam value="#arrData [5]#" cfsqltype="cf_sql_bit">,
<cfqueryparam value="#arrData[6]#" cfsqltype="cf_sql_varchar">
)
</cfquery>

<cfset i = i + 1>
</cfloop>




<cfset flash.result=true>
<cfreturn flash.result>

</cffunction>

but I see nothing in the database but get an error returned to flex:(

faultCode:Server.Processing faultString:'Element 1 is undefined in a CFML structure referenced as part of an expression.' faultDetail:''

I think I've figured out how to sent the array collection data to cold fusion. However I am not sure of the best way to save this data to the mssql database.

Any ideas?
