My environment: Windows 2000 XEmacs 21.4 jde-2.2.7.1. semantic-1.4beta5/6 eieio-0.16 speedbar-0.13 I try to load file and I get error message: "Wrong type argument: number-char-or-marker-p, nil" This happens after loading the prj.el. After the error the buffer isn't opened. Yes. I can't even see the file. I have used JDE quite heavily for two months and nothing like this has happened before. I have attached the problematic file, RemoteDebugger.java. ------ Kalle Raita <[EMAIL PROTECTED]> ---------------------- 040 - 723 1441
