Silverstripe 3.1 - onBefore/After Delete/Write doesn't work

I'm trying to execute a simple write command on onAfterWrite or before or onBeforeDelete. But it simply doesn't work.

Object1 -> here I want to execute the code. Has a $has_one relation(Item) to the Object2

public function onAfterWrite(){
    parent::onAfterWrite();

    $item = Object2::get()->byID($this->ItemID);
    $item->Title = 'test123';
    $item->write();
}

The same problem in each other onAfter/Before function. If got no error, or anything else.

Where could the mistake be?

If I'm understanding you correctly, you want to get and manipulate the Object2 record that is related via the has_one relationship to your Object1 record. Assuming you have declared your relationship in Object2 like this:

class Object2 extends DataObject{
  private static $has_one = array(
    'Object1' => 'Object1'
  );
  ...

Your onAfterWrite code in Object1 should look like

public function onAfterWrite(){
    parent::onAfterWrite();
    // use the find() method to look up the relation
    $item = Object2::get()->find('Object1ID', $this->ItemID);
    // check that the related item exists before editing
    if($item){
      $item->Title = 'test123';
      $item->write();
    }
}
