I read the other example and comments, and this is what I changed:
I edited the JSON params like this (removed JSONLiteral):
options.put("start", "aaa");
In draganddrop.js I enclosed the function definition like this:
T5.extendInitializers(function() {
function aaa() {
alert();
}
});
Then I changed afterRender() like this:
@AfterRender
public void afterRender()
{
js.importJavaScriptLibrary(as.getContextAsset("js/draganddrop.js",
null);
ajaxResponseRenderer.addCallback(new JavaScriptCallback()
{
@Override
public void run(JavaScriptSupport javascriptSupport)
{
javascriptSupport.addInitializerCall(InitializationPriority.LATE, "aaa", new
JSONObject());
}
});
}
I don't see the Ajax error. But I also don't see the Javascript function being
called. I was hoping to see the alert box on start drag.
Any ideas?

Fir me the solution was to use ut without jsonliterl, just put the name of
the fuction without brackets
