Listheader update issues with invalidatePartial

XMLWordPrintable

    • ZK 9.5.1 S1
    • None

      Steps to Reproduce

      run the code:

      <zk>
    <zscript>
        ListModelList model = new ListModelList(Arrays.asList(new String[] {"A", "B", "C"}));
    </zscript>
    <listbox id="lb" model="${model}" >
        <listhead>
            <listheader id="lh1" label="col1"/>
        </listhead>
    </listbox>
    <button label="setLabel" onClick='lh1.setLabel("Hello");' />
    <separator/>
    <button label="setLabel + replace model"
            onClick='lh1.setLabel("Hello"); model.clear(); model.add("replaced");'/>
    <button label="setLabel + clear model"
            onClick='lh1.setLabel("Hello"); model.clear();'/>
    <button label="setLabel + invalidatePartial"
            onClick='lh1.setLabel("Hello"); lb.invalidatePartial("rows");'/>
    <separator/>
    <button label="workaround (call invalidate)"
            onClick='lh1.setLabel("Hello"); model.clear(); lb.invalidate();'/>
</zk>

      1a) click "setLabel + replace model"
      1b) click "setLabel + clear model" (simpler case)
      1c) click "setLabel + invalidatePartial" (isolated case)

      Current Result

      the label of listheader remains the same after each 1st step (1a, 1b, 1c)

      Expected Result

      the label of listheader should be updated after calling setLabel("Hello")

      Debug Information

      "invalidatePartial" will not rerender head rows, only the listitems by design.

      this works when clicking "setLabel" individiually (without "invalidatePartial")

      Workaround

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