FDS only creating one item per session


Level 2
I'm using a ColdFusion data source assigned to a MS-SQL
database. The database has a primary key with data type set to
smallint, auto-increment/identity = yes.

I'm using the CFC wizard to create my CFCs and actionscript
valueObject. My application is basic so far, just a data grid and a
3-field form. When I run my app, the data grid populates properly
with the data from my MS-SQL db. I can fill out the form and submit
the data, which adds another record to my database and is
immediately reflected in the data grid. However, if I try to add
additional records, the application does not do anything. I have to
refresh my app each time I want to add a new record.

I'm using DataService to handle my data (along with FDS which
is running on my server).

here's my basic setup

import mx.data.DataService;

import mx.collections.ArrayCollection;

import valueObjects.myTable; // created by CFC Wizard

private var ds:DataService;


private var ac:ArrayCollection;

private var myObject:myTable;

private function initApp():void{ // this is called from

ds = new DataService("myds");

ac = new ArrayCollection();



private function newRecord():void{

myObject = new myTable;

myObject.col1 = field1.text;

myObject.col2 = field2.text;

myObject.col3 = field3.text;


resetForm() // just a method that clears the form fields for
additional entries


So I fill the fields out (field1, 2, 3) and hit the submit
button, which calls newRecord(). This will insert my newly created
record into my database and will also immediately display in the
datagrid. But from this point on, no new records can be added
without manually refreshing the browser.

My work-around for this is adding ds.release(); and
ds.fill(ac); after ds.createItem(myObject); While this works, it's
very clunky. Each record I add clears the datagrid and repopulates
it, creating a "flash" of the datagrid in which things disappear
and then reappear. It's only a minor cosmetic flaw, but to myself
it's an eye sore. I've created MS access db apps using the same
code and I've never had to release and refill my ds.

So what could be going on that would prevent new items from
being added? I am 100% sure that my app fails when calling
ds.createItem() twice or more times.
