Steps to Reproduce

Enter something into the textbox and call model.add(0, value) to add a row to the top.

Current Result

All rows a re-rendered, text in Textbox is lost.

Expected Result

Prior to ZK 10, adding a line by adding an entry in 1st position just had that entry be rendered and added to the front. Text in Textbox would remain unaffected.

Workaround

Ugly stuff like

if (meshElement instanceof Grid) {
            Grid grid = (Grid) meshElement;
            RowRenderer<Object> rowRenderer = grid.getRowRenderer();
            if (rowRenderer != null)

{                 Rows rows = grid.getRows();                 Row row = new Row();                 rows.insertBefore(row, rows.getFirstChild());                 rowRenderer.render(row, newEntry, 0);             }

        } else if (meshElement instanceof Listbox) {
            Listbox listbox = (Listbox) meshElement;
            ListitemRenderer<Object> itemRenderer = listbox.getItemRenderer();
            if (itemRenderer != null)

{                 Listitem listitem = new Listitem();                 listbox.insertBefore(listitem, listbox.getFirstChild());                 itemRenderer.render(listitem, newEntry, 0);             }

        }
