I created a Vorto type that uses a multimediapicker data type, but I am unable to actually add any images. The MMP is configured to start in a specific media folder, but when trying to add an image the Select Media modal window does not actually start in that folder. And if I try to drag/drop or upload an image, it just changes my browser URL to the location of the file on my local system. And if I try to click the Media link in that modal window (to go back to the root media folder), it actually redirects me to the backoffice default landing page (/umbraco/#/).

I have tried it with the Legacy Media Picker and am getting the same results. Seems my only option right now is to use a MNTP, but unfortunately that does not show the selected image in the backoffice.

I'm wondering - has anyone else has either been able to reproduce this error, or been able to successfully use the multimediapicker inside of a Vorto property?

Another thing that I've noticed is that there is an angular error in Chrome dev tools when I actually click the icon to select an image:

SyntaxError: Unexpected token b in JSON at position 1 angular.min.js?cdv=562372413:63

And I've just upgraded Umbraco to 7.5.3 hoping that might fix it, but I'm still not able to select an image.

Thanks
