System information error when error is fixed but page wasn't refreshed

[snky1987]

When you open admin panel in few windows and you do the change in the layout then system throws System Message about invalidated cache.

Then, when you fix this issue in a new window and don't refresh the old one you will still see a bar about system error but when you click on it there is no message in a pop up.

I believe it would be worth to throw a message like "All system warning have been fixed. Please refresh the page" or similar. Just in case as empty message looks a bit suspicious.

Thanks for reporting this bug. I've opened up MAGETWO-32969 internally to track and resolve the issue.

Hi @snky1987, thank you for spending time and efforts trying to make Magento 2 better!

The M2 development team has reviewed this issue and evaluated the changes you are proposing.
We believe that this is a very important and necessary improvement we should add to M2.

There are a few things we'd like to ask you to kindly address before we merge in your commits:

• Severity level - instead using the value returned from $this->getRequest()->getParam('severity'), let's go ahead and set the severity to be the "notice" level for all cases. So basically, let's set (string)\Magento\Framework\Notification\MessageInterface::SEVERITY_NOTICE as the value for 'severity' for the default message.
• Default message - let's move the declaration of default message into the if (empty($result)) block, because it will be only used here - no need to declare the default message when the $result is not empty. Basically something like this:

        if (empty($result)) {
            $result[] = [
                'severity' => (string)\Magento\Framework\Notification\MessageInterface::SEVERITY_NOTICE,
                'text' => 'You have viewed and resolved all recent system notices. '
                    . 'Please refresh the web page to clear the notice alert.',
            ];
        }

• Message content: let's use something like 'You have viewed and resolved all recent system notices. Please refresh the web page to clear the notice alert.' The reason for this is that the system notices may not always be "issues", they can also be "warnings" or simple "notices".
• We have just refactored our copyright docblocks recently, so please revert your change there and take whatever the latest upstream has.
• Please revert the code style change you proposed for the following lines:

        $this->getResponse()->representJson(
            $this->_objectManager->get('Magento\Core\Helper\Data')->jsonEncode($result)
        );

• All the other code style changes look good and reasonable

Again, we really appreciate your time and efforts, and we are looking forward to accepting your contribution!

Also we encourage use of Dependency Injection wherever possible instead of using objectManager directly:
e.g.:

    /**
     * Initialize ListAction
     * 
     * @param \Magento\Backend\App\Action\Context $context
     * @param \Magento\Core\Helper\Data $coreHelper
     */
    public function __construct(\Magento\Backend\App\Action\Context $context, \Magento\Core\Helper\Data $coreHelper)
    {
        $this->coreHelper = $coreHelper;
        parent::__construct($context);
    }

and then

$this->getResponse()->representJson(
            $this->coreHelper->jsonEncode($result)
        );

@snky1987 Did you get a chance to look at the suggested code changes for your PR?

[snky1987]

@anupdugar Hi, I will today. Recently i had too much work with eBay service in AngularJS

[anupdugar]

No problem @snky1987. Feel free to get back if you need any inputs or have any suggestions or recommendations.

Hi @snky1987, we haven't heard back from you for quite some time. To avoid closure of this issue, can you update us by end of this week?
