The most recent request in the request stack should be used, as it is most likely the request containing an exception. Fixes incorrect error pages generated inside requestAction() calls. Fixes #2746

/**
|
|
* Exception Renderer.
|
|
*
|
|
* Captures and handles all unhandled exceptions. Displays helpful framework errors when debug > 1.
|
|
* When debug < 1 a CakeException will render 404 or 500 errors. If an uncaught exception is thrown
|
|
* and it is a type that ExceptionHandler does not know about it will be treated as a 500 error.
|
|
*
|
|
* ### Implementing application specific exception rendering
|
|
*
|
|
* You can implement application specific exception handling in one of a few ways:
|
|
*
|
|
* - Create a AppController::appError();
|
|
* - Create a subclass of ExceptionRenderer and configure it to be the `Exception.renderer`
|
|
*
|
|
* #### Using AppController::appError();
|
|
*
|
|
* This controller method is called instead of the default exception handling. It receives the
|
|
* thrown exception as its only argument. You should implement your error handling in that method.
|
|
*
|
|
* #### Using a subclass of ExceptionRenderer
|
|
*
|
|
* Using a subclass of ExceptionRenderer gives you full control over how Exceptions are rendered, you
|
|
* can configure your class in your core.php, with `Configure::write('Exception.renderer', 'MyClass');`
|
|
* You should place any custom exception renderers in `app/Lib/Error`.
|
|
*

|
* @package Cake.Error
