Growl (<b:growl />) since 0.8.5

Displays FacesMessages in Bootstrap Growl style. The widget is based on Bootstrap notify by Robert McIntosh, which is available under the MIT license.

Basically, Growl is an extension of standard JSF messages, with the ability to display a message in growl style. You can configure the growl position in any of the window corner and a lot of other settings to customize your growl experience.


<b.growl /> used the Animate.css framework by Daniel Eden to (optionally) add animations to the growl. See his website for a complete list of the animations.

Severity since 1.1.2

You can filter the severities shown using the severity attribute. The attribute takes one or more comma separated lower case severity names. This can be useful if you want to distinguish between error messages and info messages. For instance, severity allows you to use this component for info messages and a b:messages for error messages.
Allowed severity names are: info, warn, error, fatal.

To escape or not to escape since 0.8.5

By public demand, we've added the escape attribute. It allows you to add HTML tags in your messages. Please note that this might be a security issue. You're responsible to make sure that hackers do not enter JavaScript code and have it executed when the page is rendered later. Therefore, BootsFaces prints a message to the console when it renders a message with escape="false" for the first time. This message can't be deactivated. We know that using HTML tags in your error messages is a useful features, but at the same time we want to make sure you're aware of the risk.
