Fabric.js: LoadFromJSON with custom class results in blank Canvas

[gjijon]

Version

1.7.7 and 1.7.9

Test Case

https://jsfiddle.net/knc1Leuz/18/

Steps to reproduce

1. Just define one class and try to load from JSON. In fiddle I use the json from example.

Expected Behavior

If I use this class to draw in canvas, the result is a rect with a label in it.

Actual Behavior

After stringify and reuse the String, the result is a canvas with no elements and no errors in console (not even the classic "klass" exception)

[gjijon]

If you change the "labeledrect" from JSON to"rect" everything is "ok"

[gjijon]

And if you change the object definition to the way that is explained here nothing of this will work. I mean, the code not even pass to calling object constructor.

you need to see how another fromObject function is made and copy it.

Thanks, I think that many people will be thankful with this.

This should be part of the docs!
