Thanks for those links, Geoff. Actually, I'm more interested in your
Grid example where you provide this component with an encoder.
http://jumpstart.doublenegative.com.au/jumpstart/examples/tables/gridwithdeletecolumn1
When I try to do likewise, my IDE complains: "Attribute t:encoder is not
allowed here". Not sure whether this is related to the problem in any
way.
As I understand it, I shouldn't be needing to explicitly provide an
encoder. The objects being sent to Grid's source and row parameters are
Hibernate entities, and the tapestry-hibernate module normally
automatically generates ValueEncoders for Hibernate registered entities.
So the exception below has me a little puzzled.
"Render queue error in BeginRender[vessel/Read:grid.rows]: Failure
writing parameter 'row' of component vessel/Read:grid.rows: Failure
writing parameter 'row' of component vessel/Read:grid: Could not find a
coercion from type [Ljava.lang.Object; to type
com.optomus.harbour.entities.Crewman."
In case it matters, all Hibernate entities have a default constructor
(thank you, Volker).
