In the code below it is not possible to get the "value" attribute of the INPUT tag after it was changed by the user. 
You can try it yourself: change the value of the first input element and then click somewhere to get the dump. You will always get the original value "bla".

You can also see that the value of the second input is updated correctly by the JavaScript snippet. But this change is also never seen in C++. 

[code]
#include <QtGui/QApplication>
#include <QtWebKit/QWebView>
#include <QtWebKit/QWebFrame>
#include <QtWebKit/QWebElement>
#include <QtCore/QDebug>
#include <QtCore/QDateTime>

class MyWebView: public QWebView {

public:

    void mouseReleaseEvent(QMouseEvent *e) {
        qDebug() << "clicked" << QDateTime::currentDateTime().toString();
        dump(page()->currentFrame()->findFirstElement("#input1"));
        dump(page()->currentFrame()->findFirstElement("#input2"));
    }

    void dump(const QWebElement& el) {
        qDebug() << QString("%1").arg(el.toOuterXml());
        QStringList attrs(el.attributeNames());
        QStringListIterator i(attrs);
        while(i.hasNext()) {
            QString a(i.next());
            qDebug() << QString("  %1 = %2").arg(a).arg(el.attribute(a));
        }
        qDebug() << QString("</%1>").arg(el.tagName().toLower());
    }
};

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MyWebView v;
    v.setHtml("<html><head></head><body><form><input id=\"input1\" name=\"input1\" type=\"text\" value=\"bla\" onchange=\"document.getElementById('input2').value = document.getElementById('input1').value\"/><input id=\"input2\" name=\"input2\" type=\"text\" /></form></body></html>");
    v.show();
    return a.exec();
}
[/code]
