Help with loadFromJSON & loadFromDatalessJSON

[TheRegge]

Hi kangax -- I am pulling my hair out trying to save a canvas state and reload it later. I am having zero success with either loadFromJSON and loadFromDatalessJSON (by the way, what is datalessJSON?). I have tried to put some elements on my canvas (they are loaded from svg), save the canvas as JSON (canvas.toJSON) into a variable. Clear the canvas, try to reload using one of the 2 methods mentioned above, and keep getting errors... I have tried from a JSON file, errors as well. My JSON was valid (I checked), but maybe not for what is expected by Canvas... it is not described in the doc, is it?

code example:

Myapp.mycanvas = Myapp.canvas.toJSON();
Myapp.canvas.loadFromJSON(Myapp.mycanvas);

The error:

JSON.parse: unexpected character
[Break On This Error] var Cufon=(function(){var k=function()....Image.fromElement.async=true})(this);

Down the line, do you think you could post an example of loading the result of a saved canvas back into a blank canvas? I have not seen anything like that in the examples, kitchensink etc...
