In the 1.1 branch, I did some minor restructuring of the StateManagerImpl to allow for JSF 1.1 and JSF 1.2 implementations to be somewhat consistent. Basically I needed to make the original saveSerializedView method private and then implement a new public saveSerializedView method which calls into it. This was done so that we could change to the new API's in the 1.2 branch while still keeping the same base implementation.
In the 1.2 branch, I took the modifications made to 1.1 and implemented and extended StateManagerWrapper. I removed the new saveSerializedView method and implemented a saveView method which calls into the private saveSerializedView method. When the SerializedView is returned, I create an object array, saving the SerializedView's structure and state in it. Returning the data in this format allows us to use the same CoreRequestStateManager in both implementations and no other modification is necessary.
