 #### Example for implementing an `IFileProcessor`
 
+The `objectID` in the `$context` comes from the form and corresponds to the objectID of the `FooAddForm::$formObject`.
+
 ```PHP
 final class FooImageFileProcessor extends AbstractFileProcessor
 {    
     #[\Override]
     public function acceptUpload(string $filename, int $fileSize, array $context): FileProcessorPreflightResult
     {
-        if (isset($context['fooID'])) {
+        if (isset($context['objectID'])) {
             $foo = $this->getFoo($context);
             if ($foo === null) {
                 return FileProcessorPreflightResult::InvalidContext;
