PDK.NET and Back Button Behaviour : Page Expired

Hi,

After upgrading to EP6.0 SPS12 to EP6.0 SPS15 we are experiencing problems with an application developed in PDK.NET (version used is PDK.NET 1 Patch 3).

We created an application in PDK.NET used to show a kind of hierarchy-drilldown tree. The iview shows a table with some data. When clicking on one of the table entries the same iview is refreshed and data 1 level down the hierarchy is shown. When pressing an entry in the table again the iview is refreshed and data 1 level down the hierarchy is shown,... This way we can drill down in the hiearchy.

Before upgrading our portal (we were on EP6 SP12) we could press the browsers (I.E. 6.0 SP2) back button to go up one level in the hierarchy,...

However since the upgrade to EP6 SP15 our users complain that they often get "<b>Page Expired</b>" error messages when pressing backbutton to go one level up in the hierarchy using the application above.

I find it hard to believe that upgrading our portal has anything to do with it.

Does anyone has the same issue? any solutions for this ?

Regards,

Igor.
