Getting Bisna to work with DoctrineCommon 2.1.0

UPATED 7/21/2011 Guilherme Blanco has updated Bisna. It now works with Doctrine 2.1.0. Just download it from github. It now incorporates the changes mentioned below as of 7/21/2011.

The Bisna library integrates Zend Framework version 1.x and the Doctrine 2 ORM; however, it dids not work properly with version 2.1.0 of the DoctrineCommon package. This article shows how to get it to work.
(actually, this article is now obsolete because Bisna now works with Doctrine 2.1.0)

Bisna can be downloaded from github. To check your version of DoctrineCommon issue this command from the command line

sudo pear list -c  pear.doctrine-project.org

If the version of pear.doctrine-project.org/DoctrineCommon is 2.1.0 (or higher), then you will need to change the startORMMetadata method in library/Bisna/Application/Container/DoctrineContainer.php.

Add the four lines of code mentioned by Ben Eberlei at https://github.com/doctrine/doctrine2/blob/master/UPGRADE_TO_2_1. Modify this section of startORMMetadata()

// snip... 
// only the relevent section of startORMMetadata is shown here
 if ($reflClass->getName() == 'Doctrine\ORM\Mapping\Driver\AnnotationDriver' 
      || $reflClass->isSubclassOf('Doctrine\ORM\Mapping\Driver\AnnotationDriver')) {

    $annotationReaderClass = $driver['annotationReaderClass'];
    $annotationReader = new annotationReaderClass($this->getCacheInstance($driver['annotationReaderCache']));
    $annotationReader->setDefaultAnnotationNamespace('Doctrine\ORM\Mapping\\');

    foreach ($driver['annotationReaderNamespaces'] as $alias => $namespace) {

          $annotationReader->setAnnotationNamespaceAlias($namespace, $alias);
    }

to look like this

  if ($reflClass->getName() == 'Doctrine\ORM\Mapping\Driver\AnnotationDriver' ||
      $reflClass->isSubclassOf('Doctrine\ORM\Mapping\Driver\AnnotationDriver')) {
      
      // For 2.1 add this line
      \Doctrine\Common\Annotations\AnnotationRegistry::registerFile('Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php'); 

      $annotationReaderClass = $driver['annotationReaderClass'];

     $annotationReader = new  annotationReaderClass($this->getCacheInstance($driver['annotationReaderCache']));

      $annotationReader->setDefaultAnnotationNamespace('Doctrine\ORM\Mapping\\');
                
     // For 2.1 add the following three lines:
     $annotationReader->setIgnoreNotImportedAnnotations(true); 
     $annotationReader->setEnableParsePhpImports(false);        
     $annotationReader = new \Doctrine\Common\Annotations\CachedReader( 
               new \Doctrine\Common\Annotations\IndexedReader($annotationReader), 
               new \Doctrine\Common\Cache\ArrayCache());

      foreach ($driver['annotationReaderNamespaces'] as $alias => $namespace) {

             $annotationReader->setAnnotationNamespaceAlias($namespace, $alias);
     }
