PageMethods and Firebug

Last night I was debugging an error in a Virtual Earth javascript library about PageMethods, I doubled checked everything and my method was decorated correctly, it was public and static….still no help IE kept giving me an error.  It turned out the error was extremely misleading.

I downloaded FireFox installed Firebug into it and browsed to my page with the error and presto, it turned out a semi-colon was missing inside another javascript snippet….took all of 2 seconds.
