Add a Map associated with each window or tab that the user is interacting with.
This would be below session scope but above page flow scope
--------------------------------------------------------------------------------------------------------------------------------------------
Key: TRINIDAD-1857
URL: https://issues.apache.org/jira/browse/TRINIDAD-1857
Project: MyFaces Trinidad
Issue Type: New Feature
Affects Versions: 1.2.13-core , 2.0.0.3-core
Environment: All
Reporter: Blake Sullivan
We currently have scopes for:
Application
Session
PageFlow
View
I propose that we add a Map associated with each window or tab that the user is
interacting with. This would slop into the scope hierarchy between the Session
and PageFlow scopes. We would also expose the storage for the current window
on the RequestContext. If no WindowManager was exposed and therefore there was
no current Window, this Map would be the SessionMap.
For high availability, each of the attributes stored in a Window's map would be
stored as separate attributes in the Session.
At least initially, we would not expose this map directly through its own
top-level windowScope EL property.
Proposed apis:
RequestContext:
/**
* Returns a Map of objects associated with the current window if any. If
there is no
* current window, the Session Map is returned.
* @return Map for storing objects associated with the current window.
* @see org.apache.myfaces.trinidad.context.Window#getWindowMap
*/
public Map<String, Object> getWindowMap()
Window
/**
* Returns the Map for storing data associated with this Window object. If
the environment is
* configured for fail-over, the contents of this Map must be Serializable.
* @return The client data storage Map.
*/
public abstract Map<String, Object> getWindowMap();
Since we would provide a default implementation of getWindowMap using import
org.apache.myfaces.trinidadinternal.util.SubKeyMap, we would also have to make
SubKeyMap public as well.
