Has anybody tested the following scenario:

• clicking on a button
• the button click triggers a javascript function opening a new window via window.open(...)
• verify if the window has been opened

I tried it with the following code:

     client.click("addGroup");

       
     // Verify the popup window exists
     WebClient webClient = jsfSession.getWebClient();
     List<WebWindow> openWindows = webClient.getWebWindows();   
       
     assertEquals("We are expecting 2 windows", 2, openWindows.size());
       
     for (WebWindow window: openWindows) {
          LOGGER.debug("Open window: " + window.getName());      
     }

Sometimes it works, when debugging the code. Is it necessary to wait until the opened window has been fully initialized?

Thanks for any help!
