Displaying JavaFX Graph through xml located remotely

Question

Hi
I am writing a application which gets a XML file thought URL and parse it and generates a JavaFX Graph.
i used HTTPRequest and PullParser
I know due to asyncronous call of HTTPRequest its not displaying the graph.
I like to know easy and effective way to creating this type of application.
I use my code in this format
imports;
var graphValues:String[]=[];
def pullParser = PullParser {
// parse xml and assign to graphValues
def httpRequest : HttpRequest = HttpRequest {
//get xml
def scene : Stage = Stage {
content: [
           BarChart3D {
//create graph and display
}If i need to write the asynchronous code inside stage then how ? sample code will be good.
is it possible to write in postinit{} block?

Hi.
One solution could be to put a message "Loading..." as the scene´s initial content.
Then at the end of the XML reading, You call a function that change the scene´s content to Your chart.
The function could look like this:
function changeSceneContent() {
    var myChart:MyChart = MyChart{};
    s.scene.content = [myChart];
}Another try could be to instantiate Your chart and bind It as the scene´s content.
var myChart:MyChart = MyChart{};
Stage {
  scene {
  content: bind [myChart]
}Cheers
