IMO, you should:
1. extend the cell to automatically switch to an isEditing() state on
some trigger
2. share something from your presenter/view/whatever with the cell to
tell it which value/index to "auto-edit"
3. trigger a redraw of the table, to trigger the auto-edit in the Cell
(this will probably be your setRowData that adds the new "record")
To access the ViewData class, the easiest is to use JSNI, which allows
bypassing access checks. For instance, when the "auto-edit" is triggered in
your overridden render() method, to create the ViewData (before calling
setViewData(context.getKey(), viewData) and then super.render()), use:
private native Object createViewData(String text) /*-{
return
@com.google.gwt.cell.client.EditTextCell::new(Ljava/lang/String;)(text);
}-*/;
