Breaking: #63453 - Changed rendering of FlashMessagesViewHelper
See forge#63453
Description
The default (render) rendering output of the Flash has been changed.
By default the view helper rendered an unordered list, each list item containing one message. This output has been adjusted and more markup has been added.
Impact
You may see unexpected formatting of flash messages.
Affected Installations
Any template using the Flash unless the attribute render is set to "div".
Be aware that the render attribute has been deprecated.
Migration
Add a custom rendering template for the flash messages, like outlined in the example, to obtain the same output as before.
<f:flashMessages as="flashMessages">
<ul class="myFlashMessages">
<f:for each="{flashMessages}" as="flashMessage">
<li>{flashMessage.message}</li>
</f:for>
</ul>
</f:flashMessages>
