My bad, I pasted my test component exception with a different event handler.
Anyhow, same exception with correct event handler.
ioc.Registry A component event handler method returned the value Block[Body
of PurchaseRequest:showone, at
classpath:org/mydomain/eprs/pages/PurchaseRequest.tml, line 18]. Return type
org.apache.tapestry5.internal.structure.BlockImpl can not be handled.
ioc.Registry Operations trace:
