Variables of Web I reports are all gone after editing it on Client tool

Dear all,

I just update my BOBJ system from SP06 to Patch level 5 for fixing problem about Java certificate. But after we finished the update, there are some problems about our web I report.

Whenever we open a Web I report on client tool, and edit it, then save it. After that, when you open it on web browser use BI LaunchPad, all variables had been assigned to that report are all gone.

I don't know why, I had checked my log file, but it does not have anything much, just error log because the Web I report cannot locate the Key (variable).

Please help me with this issue, it's really urgent.

Best regards,

Loc Nguyen
