I have this little example that compiles fine under Haxe 4.2.5 or less. With Haxe 4.3.1 it complains with:

"expression should be a field or of type State (found Int)" - for model.value in <ValStepper value={model.value} step={model.step} />

Main.hx

#if !macro
import coconut.data.*;
import coconut.ui.*;
import coconut.Ui.hxx;
import coco.*;
import tink.domspec.*;
import haxe.DynamicAccess;

import js.html.*;
#else
import haxe.macro.Context;
import haxe.macro.Expr;
using tink.MacroApi;
#end
using tink.CoreApi;

import js.Browser.document;
import tink.state.Scheduler;

class ValStepper extends coconut.ui.View {

	@:attribute var step:Int = 1;
	@:controlled var value:Int;
  
	function render() 
	  <div class="counter">
		<button onclick={value -= step}>-</button>
		<span>{value}</span>
		<button onclick={value += step}>+</button>
	  </div>
	;
}
  
class TestModel implements Model {
	@:observable var step: Int = 5;
	@:editable var value: Int = 0;

	@:transition function setStep(v) {
		return {step: v};
	}
}

class TestView1 extends coconut.ui.View {

	@:attribute var model: TestModel;


	function render() {
		return <>
			<div>
				<ValStepper value={model.value} step={model.step} />
			</div>
			<div>{model.value}</div>
		</>;
		
	}
}

class Main {
	static var model = new TestModel();

	static function main() {
		Renderer.mount(document.getElementById('app'), hxx(<TestView1 model={model} />));
		model.setStep(2);
	}
}
