We are seeing an "Error: SyntaxError. Invalid Character" when we refresh a page that includes an interactive grid. The error occurs in the IDE as well as at runtime. There is no additional detail. We looked at the debug log and it showed the same message, but nothing to suggest what is triggering it. When I recreate the functionality in APEX.ORACLE.COM, I do not get the error. So, it could be something about our data or our environment. Is there any way to dig deeper into the error message?
UPDATE: I installed Chrome and the symptoms of this problem changed. The error described below manifested itself as SyntaxError. Invalid Character in Internet Explorer but changes to SyntaxError: Unexpected number in JSON at position 1 in Chrome.
