Event "Controller found to handle request" when redirecting, does not show notification message

I've also tried another kernal event "Start dispatching request" with the same conditions and actions, the url redirect is working, but the notification still does not shown

Is that for authenticated users the same as for anonymous users?

@jurgenhaas, I think both. I've test for anonymous still not have the notification message

That's what I expected. Messages from Drupal get stored in the session to be displayed across page requests. Since anonymous users don't have a session, Drupal can't keep messages for them to be displayed on the next page request. Without a redirect, there is only 1 page request, and that's why it works there.

To validate that assumption, you may want to test this with authenticated users, there it should work.

I am sorry for not clarifying enough for my comment. I have tested out on both logged in and out, and both does not show any notification when redirecting to another page.

For my use case is actually for authenticated users, and as stated, the redirecting is okay, but the message does not shown as expected. I've attach screenshot for the ECA model setup below

I can't reproduce this problem for authenticated users. I've loaded the model you've uploaded above, and it works just fine for authenticated users, but not for anonymous users.

This is somehow strange, as I have added a couple of more messages to the model like this:

For authenticated users, all 4 messages get displayed.

For anonymous users, the bottom 2 (those without condition) get displayed, the top 2 don't. This must be something that Drupal core must be doing in \Drupal\Core\Action\Plugin\Action\GotoAction::execute where it flushes the messages for anonymous users that got collected up to that point, but not any others.

To find out in details, I guess this requires an intensive debugging session. @muaz91 any chance you could go through that with xdebug?

Hi,

It seems that the problem is occured when disabling the module bigpipe. I'm not sure why I've disabled it before. When enable the notification is shown as normal.

set this to fixed. thanks @jurgenhaas

Good finding. Shouldn't we try and make it work in all cases?

It would be great! I can help test @jurgenhaas

This is most likely related to 💬 Redirects and Drupal cache Fixed

@muaz91 seems like we can get this to work without even providing new ECA functionality. Please have a look at this comment and let us know if that works for you too. The important difference is that the event Controller found, which is used in your model, isn't the right one. We need to switch that to Response created, then it works just nicely.

It works! I've tested out with annonymous, and also with disabling bigpipe. both works.

Thank you @jurgenhaas

Thanks for your feedback, glad we've sorted this out. Will add something about this to the ECA Guide.
