f:flashMessages¶

Condition:

f:flashMessages¶
This viewhelper is for use in extensions you program yourself, as it is
intended to output error messages which are shown to the website user. For
example, a user has forgotten to fill out a required field and the relevant
Action method is connected to a server-side validator. The input is passed to
an errorAction method, which collates each error messages as a ‘Flash Message’
in turn, then outputs them all as a “bundle” at the place where you have
inserted this viewhelper.
