Oracle Forms 10g to 11g migration Error I having problems from first steps, while migrating Oracle Forms from 10g to 11g. Some of libraries dose not want to compile. the compiler just hangs up when I try to compile them, and Forms builder hangs up when I try to open them. Error signature

AppName: frmcmp.exe  AppVer: 11.1.2.1    ModName: orapls11.dll
ModVer: 11.1.0.7     Offset: 00002541


I checked libraries relations, everything looks fine. Does anybody had similar problems?
There is Oracle bug. When sometimes opening librarys in Oracle Builder 11g which is compiled with Oracle Builder 10g The 11g Builder crashes. I solved this problem by converting librarys to pld in Oracle Builder 10g and then converting them back to pll with Oracle Builder 11g.
