Opening a new window calls action methods again.

Question

Hi all,
I have a form that has a button to submit the information. For certain scenarios that submission can take over 30 seconds. So while that submission is taking place I hit <ctrl>-N on the browser to open a new window. This new window is calling the action methods associated with the submit button of the form.
My guess is that this second window is sharing the session information of the other window and therefore is sending the request flow through the state of the other view.
What can I do to handle this case?
Thanks.
Jason

If you want to open a new window besides your original window, then you have to do it with javascript. Put a code similar like this in your onClik property of your hyperlink:
window.open("faces/Page1.jsp", "","toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=400,height=450");
return false;When you click the hyperlink, it will open a second window of Page1.jsp. You can use if-else construct in javascript to choose which page you want to show.
If you want to pass a value to the second window, you can use query string like this:
window.open("faces/Page1.jsp?par1=value1", "","toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=400,height=450");
return false;Passing a field value in table component to second window:
window.open("faces/Page1.jsp?par1=#{currentRow.value['FIELDNAME']}", "","toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=400,height=450");
return false;To retrieve the parameter in the second page (in this case Page1.jsp), put this in init():
javax.servlet.http.HttpServletRequest req = (javax.servlet.http.HttpServletRequest) getExternalContext().getRequest();
        String par1 = req.getParameter("par1");After getting the parameter value, you can do the rest as your normal page, ie populating the page the way you like.
AFAIK, the only way to open a new window is through javascript only. CMIIW.
Hope that helps.
