kgepop: no error frame to pop to for AND In-flux value for a pin

Hello,

I'have a big problems with my oracle forms web.
Since we have make an upgarde from 10g to 11gr1 of our system, some forms crashe when we make a search from the menu bar.
in the log file there are these errors:

1) FRM-93652 : The runtime process has terminated abnormally.
2) FRM-93546 : external message from runtime process: kgepop: no error frame to pop to for error 600
3) FRM-93546 : external message from runtime process:                     In-flux value for a pin at 0x1f63b008
 
I've test with a button in the forms and not by the menu and it work fine.
????

thanks in advance
