it fixes the issue Unfortunately what you are doing is the only way to achieve this. I tried many experiments with the different change/dirty attributes and nothing could get me the "before" version of the record.

How to correctly call parent:: in beforeSave, beforeValidate, afterSave etc

it helps some times It depends on what you would like to do.
You should know that beforeSave and beforeValidate methods can affect the further process of saving/validation by returning true or false, whether afterSave and afterValidate - can't. You should also know that you can have not just one event handler, but any number of them, attached using attachEventHandler method. So, considering this, the place where you call parent function does matter in case of beforeSave and beforeValidate methods when you have multiple event handlers. In other cases it doesn't.

help you fix your problem I haven't worked with cakePHP specifically, but if it's similar to some other MVC frameworks, the beforeSave() and afterSave() callbacks are executed in a similar context (they belong to the same object -- a model or controller).
If that's the case, a simple solution would be to simply use a custom class property to track your data.
code :
private $custom;

beforeSave(){
   // save what you want to access later
   $this->custom = 'comparison result';
}

afterSave(){
   // retrieve what we found in beforeSave()
   $custom = $this->custom;
}

wish of those help I have a theory about what's happening, but no real evidence.
When you open an workbook, Excel makes a copy in a Temp directory. All the changes you make are made to the temp copy. When you save, it replaces the file you opened with the temp copy thereby "writing" your changes to disk. If you close without saving, it simply deletes the temp copy.
