Hi, In my app I open a popup window when the user want to see a list of codes associated with its current attribute field, i.e "zipcode - city" will display a list of zipcodes and cities. Debugging the action class that will display the popup window's content, I noted that I have lost my session and got a new one. I open my lookup window with the javascript command: window.open("/listCodes.do?attribute=city", "lookup", "minimize=no, ... etc") Do I have to pass something more in order to stay with the same session? Thanks for any suggestions. Adriano Labate
