FORM 问题：FRM-40735

fret

以前做过form，很久不做的，今天自己做了一个练习，结果报错了。后来发现，我把系统中任意的fmb打开然后点击“Run Form Client/Server”，系统都会报错。哪位高人能指点一下。
开始可能是FRM-40735: On-ERROR trigger raised unhandled exception ORA-06508; 如果把On-ERROR trigger 删除 就会报FRM-40735: PRE-FORM trigger raised unhandled exception ORA-06508.

我在想是不是我的form版本不对？还是服务器上的pll文件有问题。
