Breaking: #78477 - FlashMessageViewHelper no longer inherits from TagBasedViewHelper

See Issue #78477


The FlashMessageViewHelper has been refactored and no longer inherits from the TagBasedViewHelper.


The FlashMessageViewHelper outputs default context specific markup. Adding own classes or tag attributes is no longer possible.

Affected Installations

All installations using the FlashMessageViewHelper with tag specific attributes.


Remove the tag specific attributes and style the default output. If you need custom output use the possibility to render FlashMessages yourself, for example:

<f:flashMessages as="flashMessages">
    <dl class="messages">
        <f:for each="{flashMessages}" as="flashMessage">
           <dt>CODE!! {flashMessage.code}</dt>
           <dd>MESSAGE:: {flashMessage.message}</dd>
