Oracle Configurator runtime session 11.5.10 is not saving all the information.

Hi,

 we are in process of upgrading from 11.5.9 to 11.5.10 and have issue regarding Configurator run time session.
 
We are experiencing problem while clicking button Which display the Client deatils 
 
What we found is Session is either getting refreshed or terminated while navigating to that button.
 
Following is flow.
 
1) Launch the configurator from Quoting application (clientDeatilcx object class --initialize method gets kick off) which initialize the Utility class and add it to the ConfigParam object class. 
 
db = new utilityclasss(userName, logFlag);
confParam.addUserParam("confParamDBObj", db);
 
2) then we enter information on the product page and click on the button which pops up the jsp and it error out saying configuration object do not have info that we are looking for.
