Custom Webdynpro screen - Infinite loop on Back Button

Hello All,

I have a custom webdynpro screen which include the requested transaction's a adobe pdf also. We have just upgraded our SAP Portal. And now, we are falling into an infinite loop when we click on the Back Button on the screen. We tried to debug the back button, but it didn't work.

Is there anybodyelse has faced this problem before?

Any help would be so appreciated.

Regards,

Merve
