Hmmm, I must have set something wrong in Wonder. 
This is an app I am converting. And I need submit to redirect to work.


Here is the code:

public ERXRedirect myAjaxAction() {
  ERXRedirect redirect = pageWithName(ERXRedirect.class);
  redirect.setComponentToPage();
  return redirect;
}


Here is the exception:

WARN  NSLog  - <er.ajax.AjaxRequestHandler>: Exception occurred while handling request:

Thoughts?
Thanks

From where does this exception originate? ERXRedirect doesn't use ERXWOContext nor does it cast to it (at least in my code). Have your tried to set a breakpoint in the constructor of WOContext to see where it has been created?

Ok -

The redirect crashes with a cast error:
java.lang.ClassCastException: com.webobjects.appserver.WOContext cannot be cast to er.extensions.appserver.ERXWOContext
[2012-4-12 20:33:47 CDT] <WorkerThread0> java.lang.ClassCastException: com.webobjects.appserver.WOContext cannot be cast to er.extensions.appserver.ERXWOContext

Why would the appserver be WOContext? I thought ERXWOContext gets loaded on startup?

Thanks
James

ERXRedirect should work as it is. Alternatively you could try AjaxUtils.redirectTo() which does pretty the same.

public WOActionResults myAjaxAction() {
  ERXRedirect redirect = pageWithName(ERXRedirect.class);
  redirect.setComponent(pageWithName(MyPageToGo.class));
  return redirect;
}

I don't see any isJavascriptRedirectEnabled.

Am I supposed to anything special in the ModalBox besides just the action binding in Submit?

Thanks
