Hello Kanapat,

There's a new commons-collections runtime dependency for OpenFaces and that's why the error appears. There's no build-to-build "what's new"/migration instructions though you can watch the What's New in Nightly Builds document which covers all API changes and migration instructions since the last release (EAP2) and see which changes still must be applied to run the latest nightly build.

Regards,

Dmitry

The only important thing in this exception is that org.apache.commons.collections.functors.NotPredicate class cannot be found in classpath. I guess that it's not a DataTable-specific issue and the same NoClassDefFoundException will appear upon any attempt to use the NotPredicate class (or other class from commons-collections.jar). I suggest you to investigate what might cause the inavailability of this class. For example ensure that the version of commons-collections.jar that is included into your application does have this class in the appropriate package, or that there is only one commons collections library in your application and thus there's no potential conflict between them (we use commons collections version 3.1+, and maybe you have some old version without the NotPredicate class). Hope this information is helpful.
