SessionPropertyPersistenceStrategy Does Not Recognize Changes to Collections
----------------------------------------------------------------------------
Key: TAPESTRY-860
URL: http://issues.apache.org/jira/browse/TAPESTRY-860
Project: Tapestry
Type: Bug
Components: Framework
Versions: 4.0
Reporter: Jeremy F. Kassis
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.
