      • updateByClient

        protected void updateByClient​(java.lang.String name,
                              java.lang.Object value)
        Description copied from class: AbstractComponent
        Called when the widget running at the client asks the server to update a value. The update is caused by an AU request named setAttr (by invoking zk.Widget's smartUpdate at client).

        By default, it does nothing but log a warning message, since it is not safe to allow the client to update a field arbitrary.

        However, if you'd like to allow the update for a particular component you could do one of the following

        1. For component developers: override this method to update the field directly. For example,
          protected void updateByClient(String name, Object value) {
        if ("disabled".equals(name))
                setDisabled(name, ((Boolean)value).booleanValue());
        else
                super.updateByClient(name, value);
        2. For application developers: set an attribute called org.zkoss.zk.ui.updateByClient to be true. Then, this method will use reflection to find out the setter to update the value. Nothing happens if the method is not found.

          3. Notice: this method will invoke AbstractComponent.disableClientUpdate(boolean) to disable any update to the client, when calling the setter.

          If you want to enable the client update for all instances of a given component (though not recommended for the security reason), you could refer to here.

          See also zk.Widget.smartUpdate().
