For RC2 we mostly focused on TomEE 2.0 compatibility. Even though TomEE 2.0 is only available in a SNAPSHOT release, we're happy to see that it passed almost all of our tests and was able to run our showcase application just fine. The only place where it failed was with the viewParamValidationFailed page, but this appeared to be an issue in MyFaces and unrelated to TomEE itself.
To repeat from the RC1 announcement: OmniFaces 2.0 is the first release that will depend on JSF 2.2 and CDI 1.1 from Java EE 7. Our Servlet dependency is now Servlet 3.0 from Java EE 6 (used to be 2.5, although we optionally used 3.0 features before). The minimal Java SE version is now Java 7.
A full list of what's new and changed is available here.
OmniFaces 2.0 RC2 can be tested by adding the following dependency to your pom.xml:
<dependency> <groupId>org.omnifaces</groupId> <artifactId>omnifaces</artifactId> <version>2.0-RC2</version> </dependency>
Alternatively the jars files can be downloaded directly.
We're currently investigating one last issue, if that's resolved and no other major bugs appear we'd like to release OmniFaces 2.0 at the end of this week.
