"The currently displayed page contains invalid values."

[palador]

Since the last update, a error message appears everytime i try to open the "Chrome Theme" preferences page. The title of the error-message dialog says: "Could not accept changes", but i didn't change anything. The content of the error-message is "The currently displayed page contains invalid values.". There is only an OK-button.

When I click OK, go to another preferences-page and then back to the "Chrome Theme"-page, it is displayed correctly. But the theme still doesn't work anymore. I can change the settings now, but they won't be saved. The next time I open the Preferences-window and then the chrome-settings, the error-message-dialog appears again.

I'm using the following version of the plugin:

net.jeeeyul.eclipse.themes_1.4.0.201208220946.jar

I tried to uninstall and reinstall, but i still get the same error.

[jeeeyul]

Can you tell me what OS you using?
And If you have some error logs on Error Log view, please send them to me.

[palador]

i'm using the latest linux (xubuntu) 64bit

here is an extract of my configuration as shown in the eclipse-about-dialog / configuration :
*** System properties:

I want to see error log also. Open Error Log(Windows > Show View > Error Log), and reproduce problem.
then you will see new error log item. open the error log and paste here, please.

It seems caused by wrong preference value in previously saved.
I don't know exact reason why they stored with wrong form.

anyway,

1. Quit Eclipse
2. Remove "Your-Workspace-DIR/.metadata/.plugins/org.eclipse.core.runtime/.settings/net.jeeeyul.eclipse.themes.prefs"
3. Re-launch Eclipse.

It will reset all configurations for Theme.

I will inspect where wrong value came from, and provide fall-back solution against wrong value.

[palador]

I just tried your workaround, but it still don't work. Same error. I even tried a new, clean workspace, without success.

[palador]

Tried it with a new eclipse-installation and a new workspace. Installed your theme via marketplace. But, the error is still there.

[palador]

I just played around with the debugger. As the stacktrace says, there is a problem with the Scanner:

    public static HSB createFromString(String literal) { // literal is "0,0,0.94" (w/o quotes)
        Scanner scanner = new Scanner(literal);
        scanner.useDelimiter(",");
        HSB result = new HSB();
        result.hue = scanner.nextFloat(); // works
        result.saturation = scanner.nextFloat(); // works
        result.brightness = scanner.nextFloat(); // fails
        return result;
    }

[palador]

Ok i found the problem: it fails because I live in germany: Here, we use a comma instead a dot for numbers. So '0,94' would be correct.
Fixed example, which work for me:

public class Test {
    public static void main(String[] args) {
        Scanner scanner = new Scanner("0,0,0.94");
        scanner.useDelimiter(",");
        scanner.useLocale(Locale.US);
        System.out.println(scanner.nextFloat());
        System.out.println(scanner.nextFloat());
        System.out.println(scanner.nextFloat());
    }
}

[jeeeyul]

Thanks.
I will fix it

[jeeeyul]

Fix is available on https://raw.github.com/jeeeyul/eclipse-themes/master/net.jeeeyul.eclipse.themes.beta-updatesite/ (repo)
Thanks for very interesting information. (German locale and Scanning Issue)

[palador]

Thank you, it works now.

[jeeeyul]

It was fixed and released.
