Has anyone ever experienced something similar? or has anyone used hibernate
lazy-associations succesfully with expansions in T5?
I'm still not sure if it's a hibernate or a tapestry thing.
FYI; the error is happening in:
org.apache.tapestry.internal.services.PropertyConduitSourceImpl.readMethodForTerm(PropertyConduitSourceImpl.java:370)
and states:
Could not convert 'firstresult.poi.city.name' into a component parameter
binding: Class java.lang.Boolean does not contain a property named 'name'
(within property expression 'firstresult.poi.city.name').
