      Steps to Reproduce

      <zk>
    <zscript><![CDATA[
        StepModel model = new DefaultStepModel();
        model.add("AAA");
        model.add("BBB");
        model.add("CCC");
        model.setActiveStep("BBB");
    ]]></zscript>
    <button id="render" label="Render Stepbar"/>
    <div fulfill="render.onClick">
        <stepbar model="${model}"/>
    </div>
</zk>

      click the button

      Current Result

      Expected Result

      stepbar renders with active step as in StepModel

      Debug Information

      setComplete is called indirectly from renderProperties

      the error only happens when rendered dynamically, initial page rendering works as expected (e.g. by removing the fulfill condition in the example above)

      Workaround
