/**
 * ViewAction represents an action that displays a view according to a user-specified parameter.
 *
 * By default, the view being displayed is specified via the `view` GET parameter.
 * The name of the GET parameter can be customized via [[viewParam]].
 *
 * Users specify a view in the format of `path/to/view`, which translates to the view name
 * `ViewPrefix/path/to/view` where `ViewPrefix` is given by [[viewPrefix]]. The view will then
 * be rendered by the [[\yii\base\Controller::render()|render()]] method of the currently active controller.
 *
 * Note that the user-specified view name must start with a word character and can only contain
 * word characters, forward slashes, dots and dashes.
