OmniFaces 1.4 has just been released! A little later than planned due to all the needed remaining work on FacesViews by Arjan Tijms which he blogged further about at Easy extensionless URLs in JSF with OmniFaces 1.4. Note that the OmniFaces showcase is now by default also configured to make use of it, and that it also got a new domain name, showcase.omnifaces.org, which also references an OpenShift application, but now with the HAProxy cartridge.
UPDATE: on March 12, one day later, the GzipResponseFilter of 1.4 was been reported to have an issue in Glassfish 3. This is tracked down to an if (!committed)
block which was introduced during FacesViews testing. This change has been reverted and an 1.4.1 release is available at homepage and Maven. Please do not use the 1.4 release, but instead the 1.4.1!
Among the new things are:
Import functions
The handy
now got a new brother: the
which allows you to import all public static non-void methods of a given class (usually an utility class) into the EL scope without the need to register them individually via a custom .taglib.xml
file.
type="java.lang.Math" var="m" />
#{m:abs(-10)}
#{m:max(bean.number1, bean.number2)}
A (minor) disadvantage is that you'll miss intellisense/autocomplete in the average IDE.
Remove FacesServlet URL pattern from CSS/JS/image resources
The new UnmappedResourceHandler
allows the developer to reference CSS background images in CSS resources without the need to clutter the CSS file with #{resource}
expressions to reference CSS background images, which turned out to be a general maintenance pain when dealing with 3rd party libraries/plugins providing CSS/images (e.g. Twitter Bootstrap and several jQuery plugins).
Next to the
entry in faces-config.xml
, you only also need to manually add the standard JSF resource URL prefix pattern /javax.faces.resource/*
to the FacesServlet
mapping in web.xml
.
f:param with converter
Further, the standard
is been extended to implement ValueHolder
interface in flavor of
and thus support a Converter
. This is helpful in keeping the code DRY when you want to pass complex Java objects as a request parameter. I.e. you do not need
value="Edit Foo" outcome="/foo/edit">
name="id" value="#{foo.id}" />
anymore, but just
value="Edit Foo" outcome="/foo/edit">
name="id" value="#{foo}" />
provided that you've a @FacesConverter(forClass=Foo.class)
which returns its id
in getAsString()
.
