Thanks Bob, the combination of using MochiKit's eval and the correct
name for responseText (as opposed to response_text) fixed the issue.
Here's the final code, as a working example of a MochiKit AJAX fn
calling a Django view function:
selectEntity : function (entity)
{
try
mimeType: 'application/javascript' doesn't do what you think it does,
it's the overrideMimeType on the XHR. For JSON it doesn't matter since
it only uses responseText, I think it's only useful for setting it to
XML.
I think your problem is that XMLHttpRequest has a responseText
attribute, not res
