I am creating a prototype web app using Oracle Weblogic/ADF. I am using JDeveloper 11.1.1.6.0.
I have a basic application with one entity object and one view object. One of the requirements I is that once data is changed it must be digitally signed. I am using a applet/servlet based solution to get this done.
Once a user decides to edit an entry in the table they are taken to a page that shows a two-column form layout. On this page is a button that, when clicked, brings up an ADF dialog window. On this page there is a button called "Sign". Once the user clicks the "Sign" button some JavaScript executes that communicates with the embedded applet. This embedded applet in turn communicates with a servlet and returns a string representing a signature. This process is task-flow based.
The issue I am having is that for SOME users (IE 8, Win 7 Enterprise) once they click the "Sign" button on the popup they are shown the following popup:

If they click "OK", the page reloads and when they click "Sign" again the process repeats resulting in a loop. Initially I thought the alert was coming from IE, but upon further research it seems that the alert is coming from ADF. I have NO idea WHY they are getting this message as there are NO dependent dialogs. I have tried setting the "uncommitted data warning" to off for the document but I still get the same popup. Also the message ONLY appears for SOME users running IE 8 on top of Windows 7.
Does anyone have any ideas as to how to get this popup to stop and/or WHY it is happening? ANY help would be greatly appreciated as I am stumped.
Thanks.
