Wt

Hello,

I have switched from wt.3.3.2 to wt.3.3.4. Now I receive a 'Bad File Descriptor\" error message when posting something to a server. My code follows the example in the witty documentation. Does anybody know what's going on?

Thanks,

Michael.

void ConfigurableAnnotatorContainer::HandDownToHttpClient(std::string msg) {
    httpdialog_->contents()->clear();
    httpdialog_->contents()->addWidget(new Wt::WText("Waiting for response from server..."));
    Wt::Http::Message message2GO;
    message2GO.setHeader("Content-Type", "text/html; charset=utf-8");
    message2GO.addHeader("User-Agent", "An Application");
    message2GO.addBodyText(msg);
    Wt::Http::Client * client = new Wt::Http::Client(this);
    client->setTimeout(10);
    client->done().connect(boost::bind(&ConfigurableAnnotatorContainer::HandleHttpResponse, this, _1, _2));
    if (!client->post(formurl_, message2GO))
        std::cerr << "Post request in HandDownToHttpClient could not be scheduled." << std::endl;
    else
