------------------------------------------------
Looks like the GridSetDemo class was omitted as well. I think I can make it up.

> Key: TAPESTRY-1925
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1925
> Project: Tapestry
> Issue Type: Bug
> Components: Core Components
> Affects Versions: 5.0.6
> Reporter: Kevin Menard
> Assignee: Howard M. Lewis Ship
> Priority: Minor
> Attachments: TAPESTRY-1925.patch, TAPESTRY-1925_(2).patch

>
> Tapestry throws an exception when providing an empty collection, such as java.util.Collections.EMPTY_SET, to the Grid component as the source parameter. The message is of the form "tried to access class java.util.Collections$EmptySet from clas $PropertyConduit_XXX".
> It appears to be a case of not knowing which type of class to use, rather than just using the interface.
