I have tried using yaml or jus the config examples in http://doc.silverstripe.org/framework/en/reference/uploadfield.

But none seem to work properly as in setting custom folder or canUpload. They appear to have some effect, but don;t work.

canUpload false will remove the "from computer" option, but then when you click "from files" to pick a image form files, I get his following error in the 8javascript inspector:

Uncaught exception TypeError {} in onmatch on

and no php errors..

I tried several other uploadfield form modifications, but the only one that could work is setAutoUpload.

Does any one have any ideas?
