Ben Dinnerville updated TAPESTRY-2633:
--------------------------------------
Description:
As per the previous issue with ClassCastExceptions in
CoercingPropertyConduitWrapper, I am seeing a ClassCastException when trying to
use parent / child classes in a Grid.
I have class 1 (Campaign) and Class 2 (CCOCampaign) where Class2 extends
Class1. I return a list of Campaigns thru my business layer via a
List<Campaign> to the page.
Different to the first issue is tht i am expecting to only see the properties
of the parent class (Class1 / Campaign), but instead I get a ClassCastException
whenever a CCOCampaign is present in the List.
This looks to be the same issue as previously reported, with only the expected
outcome differing?
Cheers,
Ben
