Hi David,
having worked 10 years in Java I know how to use reflection:) Sorry it
was not obvious from my post - I was just inquiring whether there's a
GWT method that could be used in client code - some method that
escaped my search.
Anyway, I've solved this problem yesterday by writing a simple
generator that generates typed adapters for my data classes, such a
generated adapter looks like:
class Adapter<Myclass> {
setTypedObj(Myclass obj) { ... }
setValue(String fieldName, Object value) {
if("someProp".equals(fieldName))
obj.setSomeProp(value);
else ...
}
//similar for getValue
}
That way I can bridge my typed (my GWT code) and untyped (I use GXT
which uses ModelData dynamic bean) operations and still benefit from
rigorous typing.
