Setting a property of a Media-instance crashes the browser

Question

Hello,
I want to change some properties of a javaFx-Script via javascript.
All works, but when I want to set the Property "source" concatenating with "{FX.getProperty("javafx.application.codebase")}", the JVM crashes:
This is the relevant snippet from my xhtml-page:
<script type="text/javascript">
function setSource(source) {
    var app = document.getElementById("myJFXApplet");
    app.script.source = source;
</script>
This is my JavaFX-Main.class, where the Stage-Instance exists:
var codebase:String = "{FX.getProperty("javafx.application.codebase")}";
var source:String = ""
// This results the JVM-Crash: I only want that the source is concatenating with the codebase
var source2:String = bind "{codebase}{source}"

The reason it fails the first time is because there is no text in the string indicator to act upon. On the second and subsequent executions, if the text is left in the indicator, the property change will take effect. To test this, clear the indicator between each run, you will see that it does not set the colors as you desire.
So, put the text into the indicator first, then change the properties. Attached is a modification of your vi.
