I just tried the tool on a mac os x machine and there's an error:
When accessing a form from the operaciones:
org.zkoss.zk.ui.metainfo.DefinitionNotFoundException: Component definition not found: longbox in [LanguageDefinition: xul/html], [SYS file:/Applications/jboss-4.2.2.GA/server/default/./deploy/sampleapp.war/com.tmn.ejb.user.entity.AddressInfoBean.zul line 49 col 36]
Thanks for pointing that out. In fact there is a bug in the current release in terms of the support for long and byte. Later on today we'll upload a new release with the correction.
Thanks a lot!
The new release has now been uploaded. I hope it works in this new version.
