Wt

Hi,

Has anyone else had any problems calling join() on Boost threads within a Wt app? It hangs for me every time. I've got the following very simple app that is created from WRun:

#include <Wt/WApplication>
#include <Wt/WContainerWidget>
#include <Wt/WPushButton>

#include <iostream>
#include <boost/thread.hpp>

using namespace std;
using namespace Wt;

class WtThreadApp : public WApplication
{
    public:
        WtThreadApp(const WEnvironment& env) :
            WApplication(env)
        {
            setTitle("WtTest");

            WPushButton* button= new WPushButton("Start", root());
            button->clicked().connect(this, &WtThreadApp::startTest);
        }

    private:
        boost::thread m_thread;

        void startTest(void)
        {
            m_thread= boost::thread(boost::bind(&WtThreadApp::testThread, this));

            cout << "Calling join\n";
            m_thread.join();
            cout << "Joined\n";
        }

        void testThread(void)
        {
            cout << "testThread started\n";
            sleep(10);
            cout << "testThread finished\n";
        }
};

The output shows that the thread exits after the 10 second delay, but join() never completes. Can anyone suggest what might be going wrong?

Thanks.
