You've posted no code, so let me conjecture...
Foo.fx
public class Foo extends CustomNode {
    public function bar() : Void { println("Foo.bar"); }
    override function create() : Node {
        Rectangle {
            onMouseClicked: function(e) : Void {
                bar();
Stage {
    title : "MyApp"
    scene: Scene {
        width: 200
        height: 200
        content: [
            Foo {
                override function bar() { println("Main.bar"); }
}The compiler exception comes from the override function bar() in the Foo object literal. To workaround this, you just need to extend your custom node:
public class Baz extends Foo {
    override function bar() { println("Baz.bar"); }
}Then use Baz for your content.
Or, better yet,
Declare your function as a variable, then it can be easily initialized. For example, you can declare Foo like so:
public class Foo extends CustomNode {
    public var bar: function() : Void = impl_bar;
    function impl_bar() : Void { println("Foo.bar"); }
    override function create() : Node {
        Rectangle {
            onMouseClicked: function(e) : Void {
                if ( bar != null ) bar();
}And then your main would look like this:
Stage {
    title : "MyApp"
    scene: Scene {
        width: 200
        height: 200
        content: [
            Foo {
                bar: function():Void { println("Main.bar"); }
}
