ImportXmlWithProgress not updating result attribute of importjob

Question

I tried to write some code to import a large customization containing 50+ entities. I used the microsoft article 'ImportXmlWithProgress Message (CrmService) as a bases, but was not getting the output I expected.

The 'job.data' in the following code was not changing from the original parameterxml data. So this implies to me that the import was not sucessful. I imported the same compressed importexportxml using the microsoft web ui, and it worked fine. So I'm wondering why my job.data is not being updated with 'result' attributes for each entity that is imported.

Below is my method to import.

private void ImportEntitySchema()
{
    const string parameterXml = @"<importexportxml>
    <entities>
      {0}
    </entities>
    <nodes/>
    <securityroles/>
    <settings/>
    <workflows/>
         </importexportxml>";
    var importRequest = new ImportCompressedXmlWithProgressRequest
       {
        ImportJobId = Guid.NewGuid(),
        CompressedCustomizationXml = GetCompressedCustomizationXmlFromEmbeddedResource(),
        ParameterXml = string.Format(parameterXml, string.Join("\n", _entitySchemaEntityNames.Select(item => string.Format("<entity>{0}</entity>", item)).ToArray()))
       };
    try
    {
     _crmService.Execute(importRequest);
    }
    catch (Exception e)
    {
     //Error resulted from import request
    }

    // Retrieve the results of the import.
    XmlNode node;
    do
    {
     Thread.Sleep(2000);
     var job = (importjob)_crmService.Retrieve(EntityName.importjob.ToString(), importRequest.ImportJobId, new AllColumns());
     var data = new XmlDocument();
     data.LoadXml(job.data);
     node = data.SelectSingleNode("importexportxml/entities/entity/@result");
    } while (node == null);

    //code below here never gets executed because the loop continues infinitely
}

I've been looking, but haven't found any/many [useful] examples on the net of the ImportXmlWithProgress being used. Hopefully someone has used it and has an idea of how to get it working.

I remember having trouble with this message, I just can't remember exactly what the trouble was. How big is your import file? We also brewed an import utility for importing our customizations and I use the ImportCompressedAllXmlRequest synchronously (no timeout) on a BackgroundWorker thread. For large amounts of customizations you may have to look at: http://support.microsoft.com/kb/918609. We typically split up our customizations into a bunch of small imports to avoid this.

Should the XPath be "importexportxml/entities/entity[@result]"?
