Howard M. Lewis Ship resolved TAPESTRY-411:
-------------------------------------------
Resolution: Duplicate
> client:page strategy and client:app strategy conflicting with client strategy
> -----------------------------------------------------------------------------
>
> Key: TAPESTRY-411
> URL: http://issues.apache.org/jira/browse/TAPESTRY-411
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 4.0
> Environment: Windows XP
> Reporter: Kent Tong
>
> In tapestry.persist.xml:
> <contribution configuration-id="PersistenceStrategy">
> <strategy name="session"
> object="service:SessionPropertyPersistenceStrategy"/>
> <strategy name="client"
> object="service:PageClientPropertyPersistenceStrategy"/>
> <strategy name="client:page"
> object="service:PageClientPropertyPersistenceStrategy"/>
> <strategy name="client:app"
> object="service:AppClientPropertyPersistenceStrategy"/>
> </contribution>
> First, "client" and "client:page" are exactly the same. But if a persistent
> property is changed, the PageRecorderImpl will call findStrategy() and expect
> to find a single strategy. It means only the "client" strategy is updated
> with the new value, but the "client:page" strategy will keep the old value.
> When the page is rendered, both strategies are applied so the "client:page"
> strategy will overwrite the new value in the query parameters with the old
> value.
> Second, "client:app" also uses the ClientPropertyPersistenceStrategy class,
> which initializes itself from the "state" parameter, ignoring its scope. This
> is probably incorrect because this query parameter is meant for the "client"
> strategy. Again, if the persistent property is updated, it won't see the new
> value but it will still output the old value, overwriting the new one.
