Hey Max,

Thanks. Apparently, you need to enable security-trodden cookies explicitly. The latest git seems to work fine, but may need more testing on more browsers ...

Hi Koen!

Tested your changes with Firefox 4.0 on Windows and latest Chrome 10.0 also on Windows.

Firefox gives me a JavaScript error messagebox with:

Wt internal error: [Exception... "Security error" code: "1000" nsresult: "0x805303e8 (NS_ERROR_DOM_SECURITY_ERR)" location: "http://localhost:8080/test_cookies.wtjs?div=test Line: 173"], code: 1000, description: undefined

and Chrome only shows "loading..." after the click on "write cookie". In Chrome JavaScript-debugger I get the error:

XMLHttpRequest cannot load http://localhost:8080/test_cookies.wtjs?wtd=rWjmEF0EgWujN7AR. Origin null is not allowed by Access-Control-Allow-Origin.

test_cookies.wtjs POST http://localhost:8080/test_cookies.wtjs?wtd=rWjmEF0EgWujN7AR undefined (undefined)

Best regards,

Max

Hey Max,

I tested with Chrome and Firefox 4 and it works for me. This is how I tested using the widgetset feature example:

Hi Koen!

You are right, the example you tested works fine.

The problem is that I do not set the cookie in the Application constructor but in an event handler.

(In the clicked() signal of a Button for example...)

Is this possible? Because I have to wait for user input...

My Application looks like this:

@

class TestWidgetSet : public Wt::WApplication

{

Wt::WContainerWidget* myTop;

public:

TestWidgetSet( const Wt::WEnvironment& env )

: Wt::WApplication( env )

{

bindWidget( myTop = new Wt::WContainerWidget(), *env.getParameter( "div" ) );

auto myEdit = new Wt::WLineEdit;

std::string cookie;

try

{

cookie = environment().getCookie("TestWidgetSet");

}

catch( std::runtime_error& e )

{

log( "info" ) << "getCookie(): " << e.what();

}

myEdit->setText( cookie );

myTop->addWidget( myEdit );

auto p = new Wt::WPushButton( "write cookie" );

myTop->addWidget( p );

p->clicked().connect( SLOT( this, TestWidgetSet::Clicked ) );

}

void Clicked()

{

setCookie( "TestWidgetSet", "howdie", INT_MAX );

myTop->clear();

auto p = new Wt::WPushButton( "redirect" );

p->clicked().connect( SLOT( this, TestWidgetSet::Redirect ) );

myTop->addWidget( p );

}

void Redirect()

{

redirect( "www.webtoolkit.eu" );

}

};

Hey Max,

The example is actually setting the cookie from inside an event (in the greet() method connected to the button).

Hi Koen!

I tried your example.

I think my problem has something to do with my setup...

If I'm setting the cookie in the constructor of the WApplication everything works.

If I'm setting the cookie in the event handler it's not there.

Thank you Koen for your efforts.

Best regards,

Max

Hey Max,

There was something wrong with cookies and websockets. Perhaps this caused the problem ? This should be fixed in latest git.

Hi Koen!

Just upgraded to latest git.

WidgetSetMode and Cookies work for latest Safari and latest Firefox, but:

WidgetSetMode in latest Chrome (11.0.696.60 on win xp) is broken. I cannot see anything of my application and the JavaScript Debugger gives me following:

"XMLHttpRequest cannot load http://localhost:8080/test_cookies.wtjs?wtd=kAi1OzVu7oyPAOdI. Origin null is not allowed by Access-Control-Allow-Origin."

The problem is reproduceable with the originally attached test case.

Maybe you can help me.

Best regards,

Max

Hey Max,

I installed the latest chrome on Windows. I couldn't reproduce the problem (although setting the cookie didn't work properly, there seems to be something wrong with detecting support for cookies).

Nevertheless, I might have found a possible problem, in case the hosting HTML page is from a local file (file:///) and not a website. Perhaps you were testing it like that ? I've fixed this in latest git.

Regards,

koen

Hi Koen!

Tested it like this! Excuse me that I didn't told you.

I will test latest git in the next few days and give you feedback.
