[Seaside] GRPharoUtf8CodecStream dnu #json:

[Esteban Lorenzano]

Hi,

I installed Seaside31 and tried to migrate some of my apps and now I’m experiencing this DNU. 
I have this code: 

openPopoverScriptOn: canvas
	^ canvas jQuery getJson
		text: [ :stream | 
			stream json: (Dictionary new 
				at: 'title' put: self titleAsString;
				at: 'content' put: self tooltipAsString;
				yourself) ];
		onSuccess: (JSScript new
			add: (self view asClient 
				call: 'popover'with: (Dictionary new
					at: 'trigger' put: 'hover';
					at: 'html' put: true;
					at: 'placement' put: self placement;
					at: 'title' put: ((self canvas jQuery alias: 'data') access: 'title');
					at: 'content' put: ((self canvas jQuery alias: 'data') access: 'content');
					yourself));
			asFunction: #(data))

and then this DNU: 

GRPharoUtf8CodecStream(Object)>>doesNotUnderstand: #json:

I just installed vanilla seaside + REST: 

seaside3: spec
	spec project: 'Seaside3' with: [ 
		spec
			className: 'ConfigurationOfSeaside3';
			versionString: #stable;
			loads: #('default' 'REST');
			repository: 'http://smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main' ].

so… any idea?

thanks!
