No sourceSet nodes in the change event??!, help!

Question

I have Acrobat 9 pro and it comes with Lifecycle 8.2 ES
I decided to try the data drop down with an address block for a simple database hello world form.
I have read every web reference to this (on the surface) simple hello world style forms project.
In the process I’ve learned formCalc, accessors, clone(1), Ref, the XML form model, sourceSet,
binding, nodes, items, shortcut formCalc notation, form vars, defining OLEDB and OLEDB ODBC (tried both).
I’ve coded the change event at least 30 different ways using both formCalc and javascript.
I still can’t get this to work. I belive in RTFM but this has finally kicked my a** and I need some help.
I know what the problem is, I don’t believe it. The sourceSet node in the change event has 0 nodes even though I have two data connections and I can access them in the initialize event. Did they remove access to the sourceSet in the change event completly in Acrobat 9 and just didn’t tell anyone?
My database is SQL server with two tables.
A customer table with Name and CustomerID
An Address Table with CustomerId and address information
I set up the data drop down to display the Name and then in the change callback I tried to get the CustomerId
and query for the data in the second table. I’ve bound the address block data to fields in the second table and set the second table to delayed open.
I’ve tried this with every possible way of coding an accessor. When coded directly (using the intellsence thing) I get unknown accessor for the error. When using the index method and searching for it with a while, I get index out of range with an index value of 0.
Here is a formCalc version of the change callback:
========================
$host.messageBox(“In Change”)
var sName = xfa.event.newText
var sCustomerId = $.boundItem(sName)
var oDataConn = Ref($sourceSet.DataConnectionCRM.clone(1))
$host.messageBox(sCustomerId )
oDataConn.#command.query.commandType=”text”
oDataConn.#command.query.select = Concat(“SELECT [Name], Customer.[CustomerId], [AddressLine1], [AddressLine2], City, State, Zip FROM [DSD_JDEPROD].[dbo].[Customer] join [DSD_JDEPROD].[dbo].[Address] on PrimaryAddressId = Address.AddressId where Customer.CustomerId = ‘”, sCustomerId ,”‘;”)
oDataConn.open()
========================
This version of the code has the unknown accessor error at this line:
var oDataConn = Ref($sourceSet.DataConnectionCRM.clone(1))
I’ve coded this line many different ways using xfa notation, $sourceSet notation, resolveNode notation, but in the end it doesn’t matter
because this message box:
$host.messageBox(Concat(“sourceSet=”,xfa.sourceSet.nodes.items.length))
returns a 0 count in the change event.
I’ve check the XML and I have sourceSet in there and as I’ve said, the intellisense thing works and
the initialize callback works. The dropdown is correctly populated.
Note: I do realize I’m going to have to do something different in order to get the customerId as this:
var sCustomerId = $.boundItem(sName)
doesn’t work due to the way the initialize event populates the drop down. I’m sure I can fix that.
I just can’t get past the problem of no sourceSet nodes in the change event.
Thanks for your help!

I have done the samething and here is the code that I used .....are you by chance using Reader to run this form?
Paul
//get the input from the DDlist
var inName = xfa.event.newText;
if (inName == ""){
app.alert("You must enter a valid name - try again!")
var nIndex = 0;
while(xfa.sourceSet.nodes.item(nIndex).name != "DataConnection2")
nIndex++;
var oDB = xfa.sourceSet.nodes.item(nIndex).clone(1); // the node pertaining to the data connection specified
//app.alert(oDB.saveXML("pretty"));
//set up sql call to DB to get specifics about employee
oDB.nodes.item(1).query.setAttribute("text", "commandType");
oDB.nodes.item(1).query.select.nodes.item(0).value = "Select * from table1 where AcctNumber = '" + inName + "'";
//app.alert(oDB.nodes.item(1).saveXML("pretty"));
//now connect to DB and get a record
oDB.open()
//close the connection when finshed
oDB.close();
