How to mass delete Tridion MessageCenter warnings?

Question

I would like to be able to clear all the MessageCenter warnings with 1 button or click.

I noticed if I keep my browser window open and the CMS server is unavailable (I go off the VPN) then about every 1 minute I get a new message in the MessageCenter like '/WebUI/Models/TCM54/Services/Workflow.svc/GetListActivityInstances failed to execute. STATUS (0):'

I'm using 2013 SP1 and would like to see if it's possible to:

• Get a list of the MessageCenter items using the Tridion JS Anguilla API
• For each item in the list, remove it from the MessageCenter

Answer 1

You got your wish :)

In SDL Web 8, there are now buttons to Mark All as Read and Remove All messages. The latter only appears on the Show All tab.

Answer 2

My guess is that it's not possible to delete the messages entirely, only to set them to Archived. If you execute the following line of code in your browser console, you should see the messages go from orange to grey.

Tridion.MessageCenter.getMessages().forEach(function(message){message.doArchive();})

Perhaps even handier than the console, is to add it as a "bookmarklet" by creating a browser bookmark with the following code as its target .

javascript:(function() {Tridion.MessageCenter.getMessages().forEach(function(message){message.doArchive();})})();

Answer 3

Following up on top of Dominic's answer, if you want to remove the items from the list you can also call the dispose method.

$messages.getMessages().forEach(function (message) {
    message.doArchive();
    message.dispose();
});

Note that you'll still want to call the doArchive() method first, else you'll end up with no items in the list but the notification number will still show a count for unarchived messages.

If you wanted to only dispose the archived messages, you could do the following:

$messages.getMessages().forEach(function (message) {
    if (!message.isActive()) {
        message.doArchive();
        message.dispose();
    }
});

Also note that even though dispose() removes it from the list in the GUI, the getMessages() method still returns these. Just like the doArchive() method sets the message.properties.inactive property to true, the dispose() method sets the message.properties.disposed property to true. You can check these properties accordingly.

Hope that helps!

There is more correct way of messages deletion:

$messages.getActiveMessages().forEach(function (message) {
    $messages.executeAction("archive", message.getID());
});
