InfoPath Dev

I am extremely new to Infopath, but learning by making mistakes.

Here is the code I have so far:
function XDocument::OnLoad(eventObj)
{
XDocument.DOM.selectSingleNode("/myFields/CallAuditID").text = System.Guid.NewGuid()
}

Any assitance would be great. I have read up on the forums, but still confused.

Hi Paul and welcome to the forums! I don't see anything blaringly wrong with this - what error are you getting?

The Error:
XDocument.DOM.selectSingleNode( . . . ) is undefined

Additional information on error:
'XDocument.DOM.selectSingleNode(..)' is null or not an object.
File:script.js
Line:77

Is there another way to generate this GUID field on load or during the submission the the SQL Server.

Just for an update to everyone, I have fixed the undefined system error. The following changes to the namespace:

//<namespacesDefinition>
XDocument.DOM.setProperty("SelectionNamespaces", 'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:s0="urn:sap-com:document:sap:rfc:functions" xmlns:dfs="http://schemas.microsoft.com/office/infopath/2003/dataFormSolution" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns1="http://schemas.xmlsoap.org/wsdl/" xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2004-06-03T02:08:05" xmlns:xd="http://schemas.microsoft.com/office/infopath/2003"');
//</namespacesDefinition>

Also, I am using the function to generate the GUID as follows by a click of a button:
//==================
// Magic GUID Click
//==================
function CTRL53_7::OnClick(eventObj)
{
// Create GUID in Call Audit ID Field
XDocument.DOM.selectSingleNode("/dfs:myFields/dfs:dataFields/d:tblCallAuditStorage/@CallAuditID").text = System.Guid.NewGuid()
}
//==================

Now the error is:
The following error occurred:
Reference to undeclared namespace prefix: 'd'.
File:script.js
Line:46
Unspecified error

Line 46 is the line with the location of the field on the form to enter the GUID. is the code wrong for that portion of the feild location?

Thanks
Paul

Hi,

I think you have given incorrect prefix of field /d:tblCallAuditStorage,
Give this /dfs:tblCallAuditStorage.

I hope this will work for you.
Thanks.

K.Ramana:
Thanks for takin a look at the code. If I change the "d" to "dfs", I come up with the error:
'XDocument.DOM.selectSingleNode(...)' is null or not an object.
File:script.js

If I leave it as the "d", i get this error
Reference to undeclared namespace prefix: 'd'.
File:script.js

So, any other ideas? Is it possible since the field is the GUID field that is submit to the database, I need a "dummy" field to gather the GUID string, then have the @CallAuditID equal that field by the click of a button?

is there another way to call the field?

Hi,

Check once your Xpath
XDocument.DOM.selectSingleNode("/dfs:myFields/dfs:dataFields/dfs:tblCallAuditStorage/@CallAuditID") is correct?

I hope this will help you.
Thanks.

Add this line to your namespaces:

xmlns:d="http://schemas.microsoft.com/office/infopath/2003/dataFields"
