Flash message doesn't work in element or layout

I cannot get the Flash message to appear in an element or in a layout. However, it works fine in a template.

I have the following code in my element, layout and template:

<?= $this->Flash->render();?>

When I create an error, it displays fine when called from a view, but it doesn't work from an element or my layout file.

The idea is to load the Flash message on top of a form, that is generated using an element in the left side nav in my layout.

It would appear that calling more than one Flash->render() clears the session for the other subsequent calls.

I just have to figure out the best way to limit which Flash->render() to call. For instance, wrapping the Flash->render() in an if statement in my element. There's also the possibility to key individual Flash messages that I'm investigating.

My solution

Setting the flash:

$this->Flash->error(__('Invalid credentials, try again'), ['key' => 'element']);

In my element:

<?= $this->Flash->render('element')?>
