Does any one know solution to this problem. I too am facing similar problem.
I have a page with data table --- I open a new modal dialog window (window.showModalDialog) on click of menu item on a page --> It opens the page to view details of the item. When I close it and select different row of the table and open to see the details it shows the previous data
The data on the form fields are populated from a backing bean which is session scoped. I am sure the backing bean is updated with new data. Only that it is not displayed/refreshed in the page rendered.
Thanks for your time.
