I managed with the change of Tapestry from 5.0.2 to 5.0.4 with replaceing AppModule.java with new file. I got new AppModule.java file from temporary Maven project created with quick-start archetype. The las change was in the hilo's pom.xml to <tapestry-release-version>5.0.4</tapestry-release-version>
BR, PD
