Leonardo Uribe commented on MYFACES-3540:
-----------------------------------------

That param is for backward compatibility with the old behavior of StateManager in MyFaces. Maybe some change done causes the problem but it is not a big deal, because there are no known cases that requires this behavior (in theory a StateManager wrapper could rely on this behavior).

> Setting the parameter org.apache.myfaces.HANDLE_STATE_CACHING_MECHANICS to false results in a blown up view state on client side.
> The content of javax.faces.ViewState is > 10 times larger.
> Comparison:
> HANDLE_STATE_CACHING_MECHANICS = true
>   Request content length: 2369 bytes
>   Response content length: 1849 bytes
> Same operation with HANDLE_STATE_CACHING_MECHANICS = false
>   Request content length: 28095 bytes
>   Response content length: 25783 bytes
> There seems to be something wrong with the state saving.
