/*
|
||
|
|
* This is a page class that is used for adaptive error formatting for mobile
|
||
|
|
* devices.
|
||
|
|
*
|
||
|
|
* NOTE: We explicitly override the state management methods because if the
|
||
|
|
* normal page class is used, an exception is thrown for mobile devices.
|
||
|
|
* For example, WmlPageAdapter uses SessionPageStatePersister
|
||
|
|
* for persisting view state. SessionPageStatePersister requires
|
||
|
|
* Context.Session to be available. Otherwise, it would throw in the
|
||
|
|
* constructor. However, when an error occurred, Context.Session is
|
||
|
|
* removed by SessionStateModule before the error is being formatted and
|
||
|
|
* rendered. Hence the methods are overridden below and ignored to avoid
|
||
|
|
* the exception since there is no need to persist any view state for the
|
||
|
|
* adaptive error page which is created dynamically during error handling.
