OpenXava is a framework to develop AJAX JavaEE/J2EE applications rapidly and easily. It allows you to define applications only with POJOs, JPA, and Java 5 annotations. It is feature rich and flexible. It generates JSR-168 portlet applications (Liferay, WebSphere Portal, Jetspeed, etc.).
This release added IWithMessage, which is implemented by validators to get the messages from @Required, @PropertyValidator, and @EntityValidator. The new layout engine was improved, though it is still in beta and deactivated by default. Many bugs were fixed, including issues with @Inject in "on change" actions, storing of columns in collections with @AsEmbedded, and some IE problems
