vaadin-recaptcha's Issues

Vaadin 7.4

Still getting a similar Exception as in issue #3 with the new version 1.2.0. It occurs when entering text in the recaptcha, and then clicking somewhere else. I use Vaadin 7.4.0, Java 8 64 bit and Tomcat 7 on Windows 7.

EDIT: Can't reproduce it now, probably the widgetset wasn't compiled correctly

java.net.UnknownHostException: api-verify.recaptcha.net

Hi,

I'm getting a java.net.UnknownHostException: api-verify.recaptcha.net when using the component from my server. It was working fine one week ago, but since last couple of days I'm getting this error on my production server, in localhost it works fine with the same key and I generated the key using the server host name. ¿What's changed in the last days? appreciate any help.

ReCaptcha blocks Shortcuts (key events)

com.vaadin.ui.AbstractComponent#addShortcutListener from other components in the same UI will be blocked by clicking the ReCaptcha since the JS doesn't correctly send response back for the key event.

E.g. in the online demo if you press enter right after checking ReCaptcha, nothing will happen because key event enter is blocked by the JS component. You have to click somewhere else to change the focus back to a correct Vaadin component and press enter, then the user will be logged in.

Right now we have a workaround that always changes the focus back to the parent UI every time responseChanged:

        addFunction("responseChanged", arguments -> {
            response = arguments.getString(0);
            getUI().focus();
        });

But I think the clean fix would be for the JS to handle the key events properly

Captcha doesn't validate letters in Images

Hello.

People of QA in my proyect detect that this kind of captchas (letters in images) doesn't get validated as well as other kind of captchas. they could write anything and the captcha pass. We want to know if is an Issue with you or with google.

Uploading Captcha 1.jpg . . .

Cannot validate second captcha after validation of the first one without refreshing the page.

Hi everybody!

I have an issue using the addon.

What I do:

  • I create ReCaptcha component and add it to my vaadin application page.
  • I validate it, everything works fine.
  • I recreate ReCaptcha component and add it to my page again, because some of the user actions need to be validated with captcha every time.
  • Now there is no way to make captcha valid. It stays invalid until I refresh the browser page.

I tried to use reload() method, it didn't help.

Could you help me? Why is it happening?
