Uncaught exception: Invalid type in JSON write (NSImage) #164

Closed asciiz closed 10 years ago

I got the following exception when trying to sync. The entity contains an image attribute (NSImage, transformable).

Yes, I just came across the issue myself. Clearly a bug. I am fixing it now.

I assume this is for Ensembles 2. I just pushed a fix to the master. If you have a source code license, I can give you access. Otherwise I can build you a library. Maybe best to email info@mentalfaculty.com
