EP: XMLDocument::createBlank вызывает ошибку

[Murlin]

Доброго времени суток
вот такая ошибка валится когда внутри weblet вызывается метод XMLDocument::createBlank()

    runWebletItem    Microsoft Dynamics.

Вот сам собственно код

public void run(Args args)
{
    IISRequest    req;
    ComVariant    l,b;
    XMLTextReader   xmlReader;
    XMLDocument     xmlDoc;
    str             xml;
    BinData         binData;
    XMLParseError error;
    AscIIIo         ascIIo;
    ;
    setLogInfolog(NoYes::Yes);
    req = new IISRequest();
    l = new COMVariant();
    l.long(req.totalBytes());
    b = req.binaryRead(l);
    binData = new BinData();
    binData.setVariant(b);
    xml = binData.getStrData();
    xmlDoc = XMLDocument::newBlank();
    ascIIo = new AscIIIO(strfmt("C:\\%1a.xml",timenow()),"W");
    ascIIo.writeRaw(xml);

}

как это победить?
