Hi,

I work with InfoPath and JavaScript.

I have got Form with data source from WSS (name is "sccustomerUpdate").

When in my code I call this secondary source I have this error : Reference to undeclared namespace prefix : 'dfs'


However, I change data source view :

XDocument.DataObjects.Item("sccustomerUpdate").Query();
var try = XDocument.GetDOM("sccustomerUpdate");
XDocument.UI.Alert(try.documentElement.selectSingleNode("/dfs:myFields/dfs:dataFields/dfs:sccustomer/@PAM").Text);


How can I do ?

Thank for you help.

Hi (Salut),

Welcome on board!

I have the code for c# :

try.setProperty("SelectionNamespaces", "xmlns:dfs=\"http://schemas.microsoft.com/office/infopath/2003/dataFormSolution\"");

but I think it's a things like this for Jscript:

try.setProperty("SelectionNamespaces", 'xmlns:dfs="http://schemas.microsoft.com/office/infopath/2003/dataFormSolution"');

Bonne Chance

Haha, I ran into this error when I started with InfoPath too, it took so long to figure out what was going on! It happened to me and by the looks of it to Michel because of copying from code examples and tutorials without really knowing what was going on. Anyway, here's further reference for namespaces:

Hi,

Thanks for your help. I didn't have this error, however, infoPath return me empty string whereas I should have a value.

I wrote :

var nodeCustomer = eventObj.Source.nodeValue;
XDocument.UI.Alert(nodeCustomer);//return a good value

XDocument.DataObjects.Item("sccustomerUpdate").Query();
var myList = XDocument.GetDOM("sccustomerUpdate");
myList.setProperty("SelectionNamespaces", 'xmlns:dfs="http://schemas.microsoft.com/office/infopath/2003/dataFormSolution"');
XDocument.UI.Alert(myList.selectSingleNode("/dfs:myFields/dfs:dataFields/dfs:sccustomer[@Title='" + nodeCustomer + "']").Text); // return empty string


Some body has an idea ?

Salut,

Are you sure that the namespace is always the same for:

XDocument.UI.Alert(myList.selectSingleNode("/dfs:myFields/dfs:dataFields/dfs:sccustomer[@Title='" + nodeCustomer + "']").Text);

I think it's tns: not dfs for this one!
