Hi
You can use AjaxResponseRenderer and pass the variable to an initializer method
(which you have to write in javascript).
@Inject
private AjaxResponseRenderer ajaxResponseRenderer;
@OnEvent("eventLinkEventName")
void myEventHandler(){
ajaxResponseRenderer.addCallback(new JavaScriptCallback(){
public void run(JavaScriptSupport javascriptSupport){
JSONObject spec = new JSONObject();
fill_spec_with_json();
javaScriptSupport.addInitializerCall("MyInitializerMethod", spec);
}
});
}
P.S. : Code Not Tested
regards
Taha
