Re: Local Forward with Parameters Causes Exception
The parser doesn't know what you want, it only knows what it sees. :-) In this case, it had started parsing an XML entity reference - something like amp; - and found a parse failure for the reference because it expected to see sortBy; instead of sortBy=. That is, it expected a semicolon, but what it got was an equals. -- Martin Cooper - Original Message - From: Thomas Quas [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, August 28, 2001 10:42 PM Subject: Re: Local Forward with Parameters Causes Exception Thanks all, problem solved.
