    Description

      Steps to Reproduce

      run the code:

      <zk>
          <zscript>
              ListModelList model = new ListModelList(Arrays.asList(new String[] {"A", "B", "C"}));
          </zscript>
          <custom-attributes org.zkoss.zul.listbox.rod="false"/>
          <listbox id="lb" model="${model}" >
              <listhead>
                  <listheader label="col1"/>
              </listhead>
          </listbox>
          <button label="hide" onClick="lb.setVisible(false);"/>
          <button label="show" onClick="lb.setVisible(true);"/>
          <separator/>
          <button label="show + replace model"
                  onClick='lb.setVisible(true); model.clear(); model.add("replaced");'/>
          <button label="show + clear model"
                  onClick='lb.setVisible(true); model.clear();'/>
          <button label="show + invalidatePartial"
                  onClick='lb.setVisible(true); lb.invalidatePartial("rows");'/>
          <separator/>
          <button label="workaround (call invalidate)"
                  onClick='lb.setVisible(true); model.clear(); lb.invalidate();'/>
      </zk>
      

      1) click "hide" (hides listbox)
      2a) click "show + replace model"
      2b) click "show + clear model" (simpler case)
      2c) click "show + invalidatePartial" (isolated case)

      Current Result

      the listbox remains invisible after each 2nd step (2a, 2b, 2c)

      Expected Result

      listbox should become visible after calling setVisible(true)

      Debug Information

      the AuResponse is missing the command to change the visibility, when "invalidatePartial" is triggered

      e.g.: ["setAttr", [{$u: "kJxP0"}, "visible", true]]

      this works when clicking "hide" -> "show" individiually (without "invalidatePartial")

      Workaround

      call listbox.invalidate() manually to trigger a full component rerender
