We needed to disable view pooling for certain views because we noticed issues with "static structure" views when using ViewScope. Our ViewScope beans are available in our controller code, but are no longer available during the RenderResponse phase in our xhtml pages - via expression language lookups.
- On the very first request to the view (before its placed in the pool), the
state is applied correctly - but then every subsequent request to the pooled
view doesn't have the correct view state.
- It looks like the view state hasn't been correctly applied on the view
after its retrieved from the pool.
Ways we've been able to work around this issue:
- If we disable view pooling for these views, then the beans are correctly
available in ViewScope.
- We don't see this issue on any of our "dynamic structure" views - in fact,
if we convert the static structure view to a dynamic structure view (via an
extra ui:include with EL, etc), then the view state is mapped correctly and the viewscope beans are available.
