The WAE is developed using asp.net
I am trying to navigate the transactions using OPENSTA but
there is place where i should get a pop up message with an
'ok' button but the pop up always displays the following error.
"page cannot be displayed"
when I tried the same transaction manually it works fine.
Does a script get generated? If so, post it as an attachment. I suspect you are being redirected to an https url and the recording gateway is not handling it correctly. If that is the case, you can try starting the recording in https mode or better yet, if you control the web site, turn off https to make the recording and then edit the scripts substituting https:// for http://.
