    I have pretty much classes in my project already. Just wanna keep their count minimal. Creating a separate component class for dumb components that does not contain any logic seems too much for me. Again the logic is contained withing a certain State like this LobbyState. I wanted to render UI and handle all the clicks withing my LobbyState.
  • k
    For more complex components it's fine to create a separate class. I agree.

    @User btw linux target with access to button by id is also compiled but just exits application without any visible stacktrace or exception 🙂
  • f
    Try running it with gdb for a stack trace
  • f
    gdb yourbuild
    (in the build folder) 
    run
    bt
  • k
    hmm ok
  • k
    Copy code

    Have no clue what ValueException is related to.
  • f
    😬 Not super useful 😐 Worth a shot. I'm all out of ideas I'm afraid!
  • k
    The code that fails now is:
    Copy code
    private function onReady(event:UIEvent):Void
    {
        trace('onReady -> ui:', ui);
        trace('onReady -> event:', event);

        ui.joinButton.onClick = function() {
            if (isValidName())
            {
                switchToNextState();
            }
            else
            {
                trace('Player name invalid');
            }
        };
    }
  • k
    Yeah. me too ))
  • k
    The code inside the onClick handler is not called.
  • k
    So it's not related.
  • f
    Can you trace 
    ui.joinButton
    ?
  • k
    null
  • k
    so this is the ValueException from
  • k
    so strange because joinButton is there
  • k
    oh maybe onClick="" is the case now. it was added when I first found that joinButton is null ))
  • k
    no. does not help.
  • k
    Ok, you've tried a lot. Thank you so much for your time. Maybe something is broken with buildComponent idk. Or it just works the other way.
  • f
    Was afk - no worries. Strange stuff. Good luck!
  • b
    Still having issues @User ?
  • k
    @User yes the same )
  • k
    any suggestions you can provide?
  • b
    So, just to understand the problem, you want to refer to items in your xml by id in a haxe class?
  • k
    Ok. At first I've asked here how to pass some context into a pure xml component and to call the method on a context variable from onClick.
  • k
    5Mixer suggested to refer to a button by id
  • b
    you mean calling a haxe class from inside a xml file? Something like 
    <button onClick='myHaxeClassInstance.foo()' />
  • k
    yes, exactly
  • k
    this would be ideal solution for me but I'm open to others of course if this is not supported )
  • b
    ok, so thats not really possible, im open to suggestions on how to achieve that and what that would look like from your perspective, its useful, but its also using script, which is less that ideal i would say, the issue, is how to pass "myHaxeClassInstance" to the component (as a script var)... Ill have another thing though, in the mean time, you might think about "reversing" that and having a haxe class do the heavy lifting, example:
