Description

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.
