Does anyone know if there are 'pimcore-exceptions' or do I have to throw the Zend Framework- or PHP-exceptions?
I've scanned their GitHub-repository but found no hint.
Thanks!
There are only a couple of pimcore-specific exceptions (take a look at pimcore/config/autoload-classmap.php):
For common use cases stick to the Zend exceptions, using plain PHP exceptions (and/or define your onw) where none seem appropriate.
