WORK PROPERLY WITH ZK 8.0.0-EVal version !!!!!

for me the problem happens because the method org.zkoss.zk.ui.util.Configuration.addListener with the arg klass = org.zkoss.zuti.bind.ZutiPhaseListener is called before the same method with the "klass" arg org.zkoss.bind.init.ZKBinderPhaseListeners.

=> So org.zkoss.zk.ui.util.Configuration._aggregations is not initialized !

i tested by generating a Maven project with the zk-ee-eval-archetype-webapp-spring-jpa :
spring.version : 4.1.2.RELEASE
hibernate.version : 4.3.5.Final

change database to com.h2database:h2:1.4.190

debug info

• zuti.jar/config.xml is loaded before zkbind.jar/config.xml which causes the bug (this does not always happen it depends on an undefined class loading order)

workaround

modify the zuti.jar\metainfo\zk\config.xml

<config>
 <config-name>zuti</config-name><!-- used to resolve dependency -->
 <depends>zkmax,zkbind</depends>
..
</config>

this ensures the config.xml in zuti.jar is loaded after the config.xml in zkbind.jar
