Wt

When i try to integrate a simple widget from a wt server (with widgetset entrypoint) in a website(wt server)

@Konstantin Malanin std::string *div = env.getParameter("div");

std::string defaultDiv = "div";

if (!div)

div = &defaultDiv;

auto app = cpp14::make_unique(env);

if (div) {

app->setJavaScriptClass(*div);

std::unique_ptrWt::Dbo::SqlConnectionPool UserDb = Session::createConnectionPool(app->appRoot() + "db/user.db");

std::unique_ptr uploadWidget = Wt::cpp14::make_unique(*UserDb); //same error with juste a wcontainerwidget

UploadWidget *uploadWidgetRaw = uploadWidget.get();

app->bindWidget(std::move(uploadWidget), *div);

std::string chat = app->javaScriptClass();

// + "document.body.appendChild(" + oAuthWidget->jsRef() + ");");

}

else {

std::cerr << "Missing: parameter: 'div'" << std::endl;

app->quit();

}

return app;@

on the main server that uses this widget :

auto container = this->addWidget(std::make_unique<WContainerWidget>());
container->setId("container");
container->doJavaScript("loadScript('//www.exemple.com/upload.js?div=" + container->id() + "', null);");
