Subject [jira] Created: (TAP5-668) BeanModel throws exception when adding new field to model

BeanModel throws exception when adding new field to model
---------------------------------------------------------

                 Key: TAP5-668
                 URL: https://issues.apache.org/jira/browse/TAP5-668
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.0.18
            Reporter: Charles Fineman
            Priority: Minor


Following examples I've found on the web I created the following method in a Page class so
I could have additional columns appear in the grid component:

	public BeanModel getModel()
	{
		BeanModel<Experiment> model = beanModelSource.createDisplayModel(Experiment.class,
resources.getMessages());
		model.add("edit");
		model.add("delete");
		return model;
	}

A RuntimeException is throw within the call to model.add("edit"). It complains that the "edit"
property does not exist. If I pass 'null' as the conduit (i.e. model.add("edit", null) ) It
works fine.
The JavaDoc seems to indicate that I can just add a new property to the model using the original
form of the call but it seems to not working that way in 5.0.18.
