You are right. Setting typehint to String should fix it.  

@this-that-the-otter : Thanks for sharing this. Please see if in your listener code, it is updating jcr:title property. If it is, you can try commenting it out and deploy it to your instance. That should help narrow down on what is causing this String[] issue. thanks.

@this-that-the-otter : This can happen if you have specified a typehint for your property or some specific type of field values. Can you check if there is a @TypeHint set for jcr:title property (ideally should not be the case).If not, can you share what kind of values are being set on title field. t...
