Thanks in advance

// flow.js

cocoon.sendPage("html/wait.htm");

for(var row = 0; row < repeater.getSize(); row++)
{
   var isSelected = repeater.getWidget(row,

   if (isSelected)
   {
      var msgId = repeater.getWidget(idx, "reference").getValue();
      var xpath = "/msg/msg-id[text()='" + msgId + "']";
      var dbxmlAdaptor = new 
Packages.zw.co.eswitch.adaptor.DBXMLAdaptor(xpath);
      if (submitBtn == "auth1")
      {
         dbxmlAdaptor.update("status", "AUTH-2");
         print("Message : " + msgId + " status changed to AUTH-2");
      }
   }
}

cocoon.sendPage("html/done.htm");

No. Of course that wouldn't. Firstly, you need to use sendPagaAndWait() 
in order for processing to continue. Secondly, the processing continues 
when the user has submitted the page you've sent, not as soon as the 
page has been sent.

To do this, what you'd have to do is initiate a background process to do 
the calculation, send them a page that says "please wait", and has an 
automatic refresh <meta> tag, set to, say, 2 seconds, pointing at a 
second page. This second page, when loaded, then collects the results of 
the background process.

I'm afraid, as far as I can see, there's no easy way to get around this 
using Flow.

But I'd be delighted to be corrected.
