Namespace casting problem (offline secundary datasource)

C

Charl

Hello,

I've made an Infopath form looking a lot to the DataInterop example in the
SDK. In my form I've a secundary datasource (webservice) which I would like
to make available offline, so I made a method CacheAuxiliaryDOMs() like the
DataInterop example. When executing the following line of code:

objOfflineDataNode.parentNode.replaceChild(objNewOfflineDataNode,
objOfflineDataNode);

I get the following error:

Element
'{http://schemas.microsoft.com/office/infopath/2003/dataFormSolution}myFields'
is unexpected according to content model of parent element
'{http://schemas.microsoft.com/office/infopath/2003/myXSD/2004-08-12T14:50:06}users'. line: 160

As far as I can over see the problem, I think the problem is an
casting/converting problem. I know not so much about namespaces, but it seems
that my main document source has an other namespace then my secundary
(webservice) datasource. And when I add the secundary xml data tree to my
main data tree (so that the data is saved for offline use) the exception
rises.

The question is, how to fix this error so the secundary data is copied into
the main xml tree (how to cast the xml data from one namespace to another?)?

(Below I've included the whole function CacheAuxiliaryDOMs() and the files
script.js and manifest.xsd and getMedewerkers.xsd if it's needed to help me)

Thanks,

Charl





The function where this occurs is:

function CacheAuxiliaryDOMs()
{
var objOfflineDataNode = null;
var objNewOfflineDataNode = null;
var objNode = null;

// Get the current SalesSummaryData node.
objOfflineDataNode =
XDocument.DOM.selectSingleNode("/my:mijnVelden/my:eek:fflinedata");

// Build up a XML fragment containing curent contents of the auxiliary DOMs.
// The fragment consists of the results of several XSLT transforms applied
// to the XML downloaded from the database.
objNewOfflineDataNode = objOfflineDataNode.cloneNode(false);

// Build up a XML fragment containing current contents of the auxiliary DOMs.

objNode = XDocument.DOM.createNode(1, "users",
"http://schemas.microsoft.com/office/infopath/2003/myXSD/2004-08-12T14:50:06")
objNode.appendChild(XDocument.GetDOM("getMedewerkers").documentElement.cloneNode(true));
objNewOfflineDataNode.appendChild(objNode);

// Insert the new offline data to the DOM.
objOfflineDataNode.parentNode.replaceChild(objNewOfflineDataNode,
objOfflineDataNode);
}
