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 :

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

private void redirectToHomePage () {
    Executions.sendRedirect("index.zul");
}

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.
