Message: 'JSON' is undefined
Message: 'i.reportViewer.ReportSettings' is null or not an object
According to http://stackoverflow.com/questions/5339232/json-is-undefined-error-in-ja..., IE 8 does not natively support JSON and a JSON parser must be added. I checked the source code of our 5.2 instance and sure enough, it looks like the same "flow.html" page does not use JSON directly.
I tried to follow the directions within stackoverflow but am unfamiliar with how to add the JSON.js library to the stack.
Manually changing the Document Mode out of "Compatibility Mode" seems to fix this issue. Anyway to add the JSON parser so that IE works out of the box?
