Wt

Here I want to use a custom line edit:

class MyEdit : public Wt::WLineEdit
{
public:
    MyEdit(Wt::WContainerWidget *parent = 0) :
        Wt::WLineEdit(parent)
    {
        doJavaScript(jsRef() +
                ".addEventListener('input', function() { console.log(\"input event\"); })");
    }
};

Wt::WApplication*
createApplication(const Wt::WEnvironment& env)
{
    Wt::WApplication *app = new Wt::WApplication(env);

    MyEdit *edit = new MyEdit;
    app->root()->addWidget(edit);

    return app;
}

When I load this app using Firefox 3.6.28 I get the 'loading' label in the top right corner and my app becomes unresponsive.

In the js console log I get this:

uncaught exception: [Exception... "Not enough arguments"  
nsresult: "0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)"  
location: "JS frame :: http://192.168.77.143:9097/wt?
wtd=LQOku4MYblhKT1mv&sid=-1194321923&tz=240&
deployPath=%2Fwt&request=script&rand=1172220759 :: anonymous :: line 260"  data: no]

In other browser (and in newer versions of FF) everything is ok.

I use Wt 3.3.1.

I don't know if this is Wt or Firefox bug :)
