Hi all,

I I have a zul where I must have a valid query param at that page. For the moment the code is like(simplified for readability) this :

public void init(@ContextParam(ContextType.PAGE) Page page, @QueryParam("catalog") String catalog) {
    if (null == catalog) {
    try {
    } catch (CatalogNotValidException e) {

private void redirectToHomePage () {

The problem is that the sendRedirect is never called.
I did also try :

  • Executions.getCurrent().sendRedirect();
  • change the index.zul to /index.zul to ./index.zul

I'm 100% sure that the code is triggered buut the method keep on going and I get a severe error on the page.

For the ones who want more info of the error, I set a viewmodel dynamicly and get this error :

org.zkoss.zk.ui.UiException: view model of 'vm' is null at.

Hi, I will suggest using initiator or ExecutionInit to do the validation before init the view model.

when you using initiator or ExecutionInit to do the validation, you can use Executions.forward(String)
