dang! is there any way to get that back into the framework?<br><br><div class="gmail_quote">On Fri Jan 16 2015 at 2:31:41 PM Paul DeBruicker <<a href="mailto:pdebruic@gmail.com">pdebruic@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">JQAjax used to have callback:json: but it got lost in the Seaside 3.1<br>

JQAjax>>callback: aBlock json: anObject<br>
"Register aBlock as a secondary callback. anObject is a reference to a<br>
Javascript object on the client-side. anObject will be serialized to a JSON<br>
string, sent back to the server, deserialized from JSON to nested Smalltalk<br>
objects, and result passed into aBlock.<br>
<br>
Note: The serialization of Javascript objects to JSON requires a modern web<br>
browser with native JSON support or the JSJsonDeploymentLibrary to be<br>
loaded. Objects that recursively refer to themselves and objects that<br>
contain or objects that contain methods might not be serializable and cause<br>
the web browser to loop inifinitely or throw an exception."<br>

self<br>
callback: [ :value | aBlock value: (JSJsonParser parse: value) ]<br>
value: (JSJson new stringify: anObject)<br>
