>
> Key: TAPESTRY-860
> URL: http://issues.apache.org/jira/browse/TAPESTRY-860
> Project: Tapestry
> Issue Type: Bug
> Components: Framework
> Affects Versions: 4.0
> Reporter: Jeremy F. Kassis
> Assigned To: Jesse Kuhnert
> Priority: Minor
>
> Create a page property as follows:
> <property name="foo" persist="session">new java.util.HashSet()</property>
> In a listener method, add an item to the collection. The SessionPropertyPersistenceStrategy does not record the change.
> Workaround: Resave the collection using the setter. However, when a page passes a persistent collection property to a subcomponent, the subcomponent must know to resave the collection using the setter to "hack" the Tapestry functionality. This breaks an abstraction barrier between page and component.
> Anyway, there you have it.
