--- Comment #3 from Mark Thomas <ma...@apache.org> --- OK. I see what is going on here now. A bug (now fixed) in the custom error page handling wasn't helping. Tomcat isn't clearing the buffer of the containing page when the forward happens. When Tomcat tries to write that content (after the forward) the ISE happens. I think I have a fix but I need to do some more testing of the behavior with nested tags before I commit the fix. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
