First, I am using the latest, Tapestry/Tapestry-JQuery versions: 5.3.7 / 3.3.7.
I created draganddrop.js and put it under webapp/js. It has a simple function:
function aaa() {
alert();
}
In Java, I added the code like this:
@Inject
private AssetSource as;
@Inject
private JavaScriptSupport js;
@AfterRender
public void afterRender() {
js.importJavaScriptLibrary(as.getContextAsset("js/draganddrop.js", null);
}
So the JavaScript should be imported (I successfully imported other js scripts
this way)....
Then in the same Java class I edited the JSON params to now have:
options.put("start", new JSONLiteral("aaa"));
But I got the same Ajax error, communication with the server failed: null.

I think this (passing a JavaScript parameter from the server side) is not
recommended anyway. Create this function in some .js file which you
include in your page or component then pass options.put("start", new
JSONLiteral("nameOfTheFunction"));
