Hi
Also make sure your entities are in he correct entities package <-- I think
I have same files structure as in the Tapestry tutorial:
- Address.java in entities package
- Index.java in pages package
- CreateAddress.java in pages.address package
- AppModule.java in services package
Can you give a full exception listing <--- Here is it:
- locationclasspath:com/example/jpa/pages/Index.tml, line 29
- java.lang.NullPointerExceptionHide uninteresting stack framesStack
