Question

i tried to implement the file upload via doctrine/lifecycle callbacks as described here:

http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html#using-lifecycle-callbacks

So far it works, but the PrePersist/PreUpdate Event is not fired, the function “preUpload” is not called.
Functions like “upload” and “removeUpload” triggered by other lifecycle events are called correctly.

Does anyone have an idea why the event is not fired or a solution for this problem?

Thanks
