Description

Hi,

Downloading a file and clicking around while downloading gives issues on google Chrome. It works as expected on Firefox and IE.

On Chrome it shows a 'Loading' message that doesn't appear to go away anymore. Some widgets stop responding to click events untill a full reload. It appears the application is in an inconsistent state from that moment.

To see the output: check my attached screenshot resource_issue.png

To reproduce:

steps:

  1. Click 'Resource test'
  2. Within 5 seconds: click 'click me afterwards'

code:

<begin helloapplication.h>

class HelloApplication : public WApplication

{

...

WFileUpload *upload_;

WDialog *dialog_;

class test_resource : public WStreamResource{

public:

test_resource(WObject *parent = 0);

void handleRequest(const Http::Request& request,Http::Response& response);

};

}

<end helloapplication.h>

<begin helloapplication.cpp>

HelloApplication::test_resource::test_resource(WObject *parent)

: WStreamResource(parent)

{

suggestFileName("test.tgz");

}

void HelloApplication::test_resource::handleRequest(const Http::Request& request,Http::Response& response)

{

std::cout << "click between here\n";

sleep(5);

std::cout << "and here\n";

//response.out() << "123";

}

void HelloApplication::create()

{

this->enableUpdates(true);

dialog_ = new WDialog("Upload");

WPushButton *download = new WPushButton("Resource test", root());

test_resource *res = new test_resource(this);

download->setResource(res);

WPushButton *button = new WPushButton("click me afterwards", root());

button->clicked().connect(boost::bind(&HelloApplication::handle_response, this, true));

}

<end helloapplication.cpp>

I tried 2 different Chrome versions

1: 6.0.472.63 (59945) Built on Debian 6.0, running on Debian 6.0.2

  1. 13.0.782.215 (Windows XP)

Regards!

Rob.

Forgot to add the method handle_response:

void HelloApplication::handle_response(bool available)

{

std::cout << "clicked!\n";

upload_ = new WFileUpload(dialog_->contents());

upload_->setFileTextSize(0);

dialog_->exec();

}

Hey Rob,

I've seen this too. I believe it is related to the following comment in WAnchor documentation:

If you do not want the application to terminate when the user follows the anchor, you must use setTarget(TargetNewWindow).

But that method is not available (nor applicable) to WPushButton. To be investigated.

I could work around this bug by linking the clicked signal to a Wanchor then?

As in:

Hey Rob,

Yes, that should work, and using setTarget().

Ok, I'll work around the issue with a WAnchor that is hidden. Thanx!

Hey Rob,

As I go over some refactoring in WResource, I realize that there may actually be another solution (I'll test it using your test case):

 response->setDisposition(WResource::Attachment);

Hey Rob,

Only the TargetNewWindow trick seems to help. I've implemented this now also in WPushButton.
