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.
